Organopalladium chemistry is a branch of organometallic chemistry that deals with organic palladium compounds and their reactions. Palladium is often used as a catalyst in the reduction of alkenes and alkynes with hydrogen. This process involves the formation of a palladium-carbon covalent bond. Palladium is also prominent in carbon-carbon coupling reactions, as demonstrated in tandem reactions.〔''Handbook of Organopalladium Chemistry for Organic Synthesis'' Ei-Negishi John Wiley (2002) ISBN 0-471-31506-0〕 == Organopalladium chemistry timeline == * 1873 - A. N. Zaitsev reports reduction of benzophenone over palladium with hydrogen. * 1894 - Phillips reports that palladium(II) chloride reduces to palladium metal by contact with ethylene.〔Phillips, F. C.; Am. Chem. J. 1894, 16, 255.〕 * 1907 - Autoclave technology introduced by W. Ignatieff makes it possible to carry out high pressure hydrogenation. * 1956 - In the Wacker process ethylene and oxygen react to acetaldehyde with catalyst PdCl2/CuCl2 * 1972 - The Heck reaction is a coupling reaction of a halogenide with an olefin. The catalyst is Pd(0). * 1973 - The Trost asymmetric allylic alkylation is a nucleophilic substitution. * 1975 - The Sonogashira coupling is a coupling reaction of terminal alkynes with aryl or vinyl halides. 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「Organopalladium」の詳細全文を読む スポンサード リンク
