WE LOST ANOTHER PRODUCTIVE SCIENTIST AND A FRIEND OF BORON CHEMISTRY COMMUNITY:
It is with our deepest sorrow to inform you about the death of our beloved husband and father Bernd Wrackmeyer on 9th of June 2017. We will miss him. A small family memorial service was held.
Gaby Wrackmeyer and family
Bernd Wrackmeyer (1947–2017)
Bernd Wrackmeyer died after long illness in Bayreuth on June 9, 2017, only a few weeks before his 70th birthday. He was born on July 30, 1947, in Coburg, a small town in Upper Franconia (Northern Bavaria), where he went to school, before he started to study chemistry at the Ludwig–Maximilians University (LMU) in Munich in 1966. He joined the research group of Heinz Nöth, working on boron–nitrogen compounds, and obtained a diploma in 1971 and a doctoral degree in 1973. In the same year he got married, and then went to England with a DFG fellowship to spend a year as a postdoctoral fellow with William McFarlane at the Sir John Cass School of the City of London Polytechnic, where he could collect experiences on heteronuclear double‐ and triple‐resonance NMR spectroscopy. He returned to the LMU to work on his Habilitation thesis – again in scientific interchange with Heinz Nöth. In 1983 Bernd Wrackmeyer was awarded a Heisenberg Fellowship, and in 1986 he received a call to the new University of Bayreuth, where he stayed as a professor of Inorganic Chemistry until his retirement in 2012 (and beyond).
The research interests of Bernd Wrackmeyer moved over the years from pure main group chemistry (he particularly liked boron chemistry—organoboration reactions of alkenyl‐ and alkynyl derivatives (of silicium, germanium, tin, lead, titanium, platinum), and boron clusters from small organoboranes to carbaboranes) towards more complex transition metal units, including ferrocene derivatives with various main group elements in the side chain(s). He was an experienced NMR spectroscopist for all kind of nuclei, including the heavy isotopes, such as e.g. 119Sn, 207Pb, 199Hg, 195Pt and others. In addition, he was very productive as an author of clearly written review articles and surveys. He has authored nearly 700 publications, among them one book and about 25 chapters in books. Although his research group was always small (until to a maximum of six coworkers), his scientific work will provide a permanent reminder of his important contribution to boron and, generally, to main group chemistry, as well as to the application of heteronuclear magnetic resonance spectroscopy.
Bernd Wrackmeyer always found strong support by his family, his wife Gaby and his three daughters Marcia, Marion and Marina. He was a true scientist with an encyclopaedic knowledge and a critical mind, and he combined this with his kind, friendly personality and a sense of hidden humour. Many of us who worked close with him will remember him as an always creative and encouraging friend and mentor. The chemical communities of the boron chemists and of the NMR spectroscopists will miss him as a quiet, even‐tempered but highly competent and cooperative colleague.

Sadly Professor Malcolm Wallbridge passed away on Tuesday this week. Malcolm was one of our first Professors at Warwick and really shaped the Department in its early years and throughout its growth in the 1990's. His influence on what we do today is great. He was responsible for shaping both Inorganic and Polymer Chemistry at Warwick as it is today as well as an even more wider contribution as Head of Department. The Department would be a very different place without his considerable influence. His wife and son are making funeral arrangements and a wake will be held in Scarman House on Tuesday 21st June – the department will have more details in due course. Malcolm will be sadly missed.
On May 23, 2016 Professor Dr. Igor Chizhevsky unexpectedly passed away as a result of thrombosis at the age 63. In the modern era of fast spreading and less challenging monoboron chemistry, his unexpected death is a serious blow to all of his friends, colleagues, and to all members of scientific community and, particularly, for those who are dedicated and surviving true researchers of boron cluster chemistry!
Igor T. Chizhevsky was born in Moscow in 1952. After graduating from the Chemistry Department of Moscow Institute of Oil and Gas Industry (1975), he was employed in the Institute of Organoelement Compounds in the laboratory of Organometallic Compounds headed by Prof. A. N. Nesmeyanov. In 1982 he received his Candidate of Chemistry degree (PhD). The title of his Candidate thesis was "Synthesis, stereochemistry and reactivity of functionally substituted norbornadiene–rhodium π‐complexes". From 1987 he started to work on metallacarborane chemistry within the group of Professor L.I. Zakharkin, and from 1989 in the group of Professor V.I. Bregadze. In 1991–1993 he worked as a Senior Research Associate in the laboratory of Professor M.F. Hawthorne, University of California, Los Angeles (USA). He received his Doctor of Science degree in 1999 (the title of his Dr. Sci. thesis is "Cyclopentadienyl and dicarbollyl complexes of platinum group metals with cycloolefins and related dienyl ligands"). Since 2000 he was a full Professor of Chemistry and a head of the laboratory of Transition Metals Metallacarboranes of the Institute of Organoelement Compounds of the Russian academy of sciences (RAS). Scientific interests of his laboratory focus on the organometallic chemistry of polyhedral organoboron and metallacarborane clusters, their reactivity and catalytic properties. Igor T. Chizhevsky is the author of several reviews and more than 200 papers in the fields of organometallic and metallacarborane chemistry. Since 1998 he is a member of International Committee of European Conferences on Boron Chemistry (EUROBORON), and since 2012 he is a member of the International Committee of IMEBORON. He was a leading specialist in the field of platinum group organometallic chemistry and catalysis by metallacarboranes. His works were characterized by in‐depth investigations and thoroughness. He was brilliant scientist with spacious mind. We miss him very much and our sincere condolences to his family!

Dr. Mark Fox has passed along the following message to the Boron Community. Should you wish to send a message to Ken's family, please contact Mark.
Dear fellow Boron chemists,
With sadness, this message is to let you all know that Ken Wade passed away last Sunday.
While many of us are familiar with his seminal work on skeletal/cluster electron‐counting rules, there are just as many of us that have enjoyed discussions with Ken and will miss him as a great friend.
Ken remained extremely active and was still passionate about chemistry. He visited the Durham Chemistry department last week and just had a publication accepted. A summary on his outstanding contributions to chemistry can be found at https://www.dur.ac.uk/chemistry/news/news_archive/?itemno=14142.
We are sad to hear the bad news about Professor George Kabalka's wife Beth Kabalka. Our sincere Condolences to George Kabalka and his family and we pray that she will rest in peace!

Herbert Binder was born in Germany on July 28, 1936 and received his Ph.D. degree in 1966 from Universität Heidelberg and then joined the faculty of Anorganische Chemie at the Universität Stuttgart in 1981 and remained there until his retirement in 1998. Although he maintained his residence in Stuttgart throughout, he spent his retired life in Sweden, that is the home of his wife, Rangna.
Indeed, his contribution to the halogenated boron cages and their conversion to free radical species is noteworthy. It is really sad that we lost another boron chemist on November 6, 2012 due to illness. He will be remembered in the hearts of those who had some impact of his acquaintance scientifically and socially!
The 2014 Boron in the Americas Meeting (BORAM XIV) will take place from June 15–19th on the Newark Campus of Rutgers University.
The conference venue is located less than 15 minutes from the Newark/New York (EWR) airport and in close proximity to metropolitan New York (ca. 20–30 minutes to midtown or lower Manhattan).
More detailed information coming soon…

Norman Greenwood was born in Australia in 1925 and graduated from Melbourne University before going to Cambridge. His wide‐ranging researches in inorganic and structural chemistry have made major advances in the chemistry of boron hydrides and other main‐group element compounds. He also pioneered the application of Mössbauer spectroscopy to problems in chemistry. He is a prolific writer and inspirational lecturer on chemical and educational themes, and has held numerous visiting professorships throughout the world.
Among the many stories that Professor Greenwood recounts is how his philosophy of teaching influenced his approach to writing his important textbook Chemistry of the Elements.
"The first thing that I wanted to emphasise was that chemistry was exciting, wondrous even, that when properly understood a lot of it is very straightforward, it is accessible, but it has to be presented in a reasonable form. That the facts of chemistry are astounding often, but also we have to remember that a compound might be beautiful to look at, it may be readily made or difficultly made, but might also be useful. And so I wanted to join the idea of the actuality rather than just an abstract idea of chemistry."
Greenwood and Earnshaw's Chemistry of the Elements has today been translated into several European and Asian languages, and is widely regarded around the world as being one of the most influential chemistry bibles of our time. Web of Stories is delighted to share Professor Norman Greenwood's video life story from his childhood in Australia, followed by his time as a PhD student at Cambridge University under the direction of Harry Emeléus, to his present status of Emeritus Professor of Chemistry at Leeds University. He is a Fellow of the Royal Society and a Foreign Member of the French Academy of Sciences.

With 29 chapters and 58 authors from all over the world, Boron Science: New Technologies and Applications, edited by Narayan Hosmane, will be published by CRC Press in March 2011 and is dedicated to Emeritus Professor William N. Lipscomb, Jr.(Nobel Prize in Chemistry 1976) on the occasion of his 90th birthday.
This book is the first of its kind to comprehensively cover the latest in boron science in a single source. The text addresses the application of boron in chemistry, industry, medicine, and pharmacology and explains its role in such problems as catalysis, hydroboration, superconductors, materials, and magnetic and nonmagnetic nanoparticles as well as in medical applications such as cancer therapy.
Co‐authored with his collaborators, John Maguire (USA), Yinghuai Zhu (Singapore) and Masao Takagaki (Japan), Narayan Hosmane presented to the world the first of its kind book on Boron and Gadolinium Neutron Capture Therapy for Cancer Treatment by dedicating it to Professor M. Frederick Hawthorne (Priestley Medal 2009), who is one of the founders of polyhedral boron chemistry, has dedicated his later career to curing cancer through the innovative, state‐of‐the‐art therapy, known as Boron Neutron Capture Therapy (BNCT) which is the subject of this book. Much of the progress in this experimental endeavor rests on Professor Hawthorne's work.
The book focuses on two concurrent experimental therapies in cancer treatment known as BNCT and gadolinium neutron capture therapy (GdNCT) using a variety of boron‐ and gadolinium‐based compounds. Some of the gadolinium compounds serve the dual purpose as being MRI contrast agents and GdNCT agents. The book describes why BNCT and GdNCT were not at the forefront of the clinical trials during the past seven to eight decades since the discovery of neutrons by John Chadwick in 1932 and how the latest development in the synthesis of target boron‐ and gadolinium‐based drugs have turned the area to be the hottest one and worthy of further investigation with the new clinical trials in the USA and elsewhere.

We see that boron has one more electron than beryllium and one less electron than carbon. Bill sought to learn more about the nature of the chemical bond through calculation. But the computing time grows dramatically and beyond the possible very quickly with the number of electrons, placing most carbon compounds out of reach in the 1960s. The fewer electrons the better for calculations, but the chemistry of beryllium and lithium is correspondingly less complex. That leaves boron.
