Abstract

Silenes, generated through thermolysis of acylpolysilanes, add to alpha,beta-unsaturated esters to form cyclobutanes and silylsubstituted cyclopropanes in moderate yields. Upon Si-C bond oxidation the cyclopropanes are converted directly to 1,4-dicarbonyl compounds, thus demonstrating the formal acyl anion chemistry of acyl polysilanes.

摘要

通过酰基聚硅烷热解生成的硅宾，与α,β-不饱和酯加成，以中等产率形成环丁烷和硅基取代的环丙烷。在硅-碳键氧化后，环丙烷直接转化为1,4-二羰基化合物，从而证明了酰基聚硅烷的形式酰基阴离子化学性质。
