Synthesis and chemistry of selected di- and tricoordinate organosilicon compounds

Abstract

To date, reports of silylene insertion into Si-C and Si-Si bonds are sparse, and limited to strained rings. Atwell and Uhlmann (72), in a study of the reaction of dimethylsilylene and 2-butyne, reported the isolation of 1,2-disilacyclobutene ^ (Scheme 2), that was proposed to arise by MegSi: insertion into tetramethylsilarene (^). That silylenes 'insert into the Si-C bond of staineu silacycles was subsequently ccrifirmcd by Seyferth and Vick who reported insertion of MegSi: into ^ and ^ (51).
