摘要：

A rhodium(I) catalyst triggers cycloaromatization of omega-trialkylsilylated acyclic enediynes to afford benzosilacycloalkane or vinylsilane products via 1,6- and/or 1,7-hydrogen transfer, presumably effected by radical stabilization by an alpha-silyl moiety, and via a seven and/or eight-membered rhodacycle intermediate. The addition of a catalytic amount of dimethyl maleate is essential to obtain, better yields air the products.
