Abstract

Dihydrosilanes undergo double trans-hydrosilylation with 1,4-diarylbuta-1,3-diynes in the presence of a cationic ruthenium catalyst to afford 2,5-diarylsiloles: in particular, 9-silafluorene is a good hydrosilylating agent to produce spiro-type siloles in good yield. ... Hydrosilylation of alkynes is catalysed by various transition metal complexes, and in most cases, cis adducts are formed. 5 However, a synthesis of silole derivatives by hydrosilylation of 1,3-diynes ...
