乙烯基重氮化合物非金属卡宾机制参与的反应

Non-Metallic Carbene Pathway Transformations of Vinyl Diazo Compounds

乙烯基重氮化合物是一类重要的重氮化合物.作为重氮化合物,乙烯基重氮化合物生成的金属卡宾物种能发生插入反应、环加成等反应;作为一类较弱的亲核试剂,乙烯基重氮化合物不经过金属卡宾中间体与贫电子体系或自由基发生的反应最近几年受到关注.乙烯基重氮化合物经过金属卡宾中间体的反应研究较为系统,这方面的综述较多,而乙烯基重氮化合物非金属卡宾路线参与的反应相对较为分散,迄今还没有系统的讨论.对乙烯基重氮化合物非金属卡宾机制参与的反应进行了综述,并对该领域的发展方向进行了展望.

Vinyl diazo compounds are important compounds in organic synthesis.The generated vinyl metallic carbene species undergo insertion reactions,cycloaddition,and other reactions.As a class of weak nucleophiles,the reaction of vinyl diazo compounds with electron-deficient systems or free radicals not via metallic carbene intermediates has attracted attention from chemical societies in recent years.Carbene chemistry has been well investigated and reviewed.While the reactions of vinyl diazo compounds involved in the non-metallic carbene route are relatively scattered.Non-metallic carbene pathway transformations over the past two decades of vinyl diazo compounds are reviewed.Furthermore,the prospect in this field is also discussed.
