Described herein is the first intermolecular σ-bond exchange reaction between the C-C bond of cyclopropenones and C-Si bond of (benzo)silacyclobutanes and it proceeds smoothly by treatment with either 1 mol % of a palladium or 2 mol % of a nickel catalyst. This reaction constitutes an unprecedented route for the synthesis of various sila(benzo)suberones. And it is also the first example of a σ-bond exchange reaction involving cyclopropenones.
本文描述了环丙烯酮的C-C键与（苯并）硅杂环丁烷的C-Si键之间的首例分子间σ键交换反应，用1 mol%的钯催化剂或2 mol%的镍催化剂处理时，该反应能顺利进行。此反应为合成各种硅（苯并）环庚三烯酮提供了一条前所未有的途径。并且它也是涉及环丙烯酮的σ键交换反应的首例。
