钴催化剂均相催化氢化以及脱氢反应的研究进展

Recent progress of cobalt catalysts for homogeneous catalysis(de)hydrogenation

近年来,铁、钴、镍和锰配合物催化体系在廉价金属催化领域取得了系列进展.由于其独特的性质和出色的催化性能,钴配合物在均相催化反应中最引人注目,所涉及的(脱氢)氢化反应在学术研究和化工行业中起着重要作用.本文根据氢化、转移氢化、无受体脱氢、脱氢偶联、借氢等反应类型总结了均相钴催化氢化、脱氢反应的研究进展,并概述了钴催化剂的反应性能、催化应用以及反应机理.

In recent years,the catalytic systems of iron,cobalt,nickel and manganese complexes have made a series of progress in the field of base-metal catalysis.One of the most impressive achievements is the catalysis by cobalt complexes,which has become increasingly attractive in homogeneous catalysis reactions because of its unique characteristics and outstanding catalytic performance.These reactions involving(de)hydrogenation play an important role in academic research and the chemical industry.In this paper,we review homogeneous cobalt-catalyzed(de)hydrogenation reactions according to the classified reaction types including hydrogenation,transfer hydrogenation,acceptorless dehydrogenation,dehydrogenative coupling,hydrogen borrowing,and provide a comprehensive overview of the reactivity of cobalt catalysts,their catalytic applications,and reaction mechanisms.
