Joseph Chatt, CBE FRS (6 November 1914 – 19 May 1994) was a renowned researcher in the area of inorganic and organometallic chemistry. His name is associated with the description of the pi-bond between transition metals and alkenes, the so-called Dewar-Chatt-Duncanson model. Chatt received his Ph.D. at the University of Cambridge under the direction of F. G. Mann for research on organoarsenic and organophosphorus compounds and their complexes with transition metals. He was employed at Imperial Chemical Industries from 1949 to 1962, during which time he, often in collaboration with Bernard L. Shaw, published influential work on the metal hydrides and metal alkene complexes. During this period, he reported the first example of C-H bond activation by a transition metal and one of the first examples of a transition metal hydride.〔Chatt, J.; Duncanson, L. A.; Shaw, B. L. "A volatile chlorohydride of platinum" Proceedings of the Chemical Society, London 1957, 343.〕 In the 1960s, Chatt moved to a professorship at the University of Sussex and subsequently assumed directorship of the Nitrogen Fixation Unit under the Agricultural Research Council.〔Leigh, G.J. (editor), N. W. Winterton (editor), ''Modern Coordination Chemistry: The Legacy of Joseph Chatt'', Springer Verlag (2002). ISBN 0-85404-469-8〕 Using the transition metal dinitrogen complex W(N2)2(dppe)2, his group first demonstrated the conversion of a dinitrogen ligand into ammonia. This work provided some of the first molecular models for nitrogen fixation. Among his many awards, he was recognized with the 1981 Wolf Prize "for pioneering and fundamental contributions to synthetic transition metal chemistry, particularly transition metal hydrides and dinitrogen complexes." He was elected a Fellow of the Royal Society in 1961, and was made a Commander of the Order of the British Empire.〔 In 1995, a year after his death, the Unit of Nitrogen Fixation moved to Norwich and became part of the John Innes Centre. The new building, as well as an annual lecture at the Centre, were named in his honour.〔(The Chatt Lecture )〕 ==References== 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Joseph Chatt」の詳細全文を読む スポンサード リンク
