    Abstract

    Various silacycles with vinylsilane framework are synthesized via the Lewis acid-catalyzed intramolecular hydrosilylation of alkynes. The cyclization proceeds in an endo-trans or/and in an exo-trans manner, depending on the substrate structure. This methodology is applicable to the synthesis of five-, six-, seven-, and eight-membered medium-sized silacycles. Furthermore, it is possible to obtain a silole derivative via the intramolecular hydrosilylation of the ortho-alkynyl-substituted phenylsilane 10.
