A computationalstudy of C-Hinsertionreactions between ethylbromodiazoacetate and three different substrates is presented. The mechanism of the C-Hinsertion is shown to be substrate dependent; the reaction follows either a concerted mechanism or a two-step mechanism in which complete hydride transfer precedes C-C bond formation.
介绍了溴重氮乙酸乙酯与三种不同底物之间的 CH 插入反应的计算研究。CH 插入的机制显示为底物依赖性;该反应遵循协调机制或两步机制,其中完全氢化物转移先于 CC 键形成。

substrates in regioselective rhodium(II)-catalysed C-H and Si-H insertionreactions giving α-halocarbonyl products in up to 82% yield. The halodiazoacetates are a novel class of diazo compounds that can undergo intermolecular carbenoid C-H insertionreactions, thus broadening the synthetic utility of such reactions.
