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 s ubstrate structure. This methodology is applicable to the synthesis of five -, six;, seven-, and eight-membered medium-sized silacycles. Furthermore, i t is possible to obtain a silole derivative via the intramolecular hydrosil ylation of the ortho-alkynyl-substituted phenylsilane 10.
