Silacycles play a very important role in modern organic chemistry and materials science.Construction of silacyclic skeletons via metal-mediated or catalyzed Si-C bond cleavage has attracted much recent attention.Several interesting and useful synthetic strategies have been reported in the literature.In this review,we have summarized recent developments on metal-mediated or catalyzed Si-C bond cleavage,which lead to the synthesis of silacycles,including silacyclobutenes,silacyclopentanes,silacyclopentadienes(siloles),6-membered silacycles,and their derivatives.
