The reaction of propargylsilanes with α,β-unsaturatedFischercarbenecomplexes has been investigated. The reaction provides 1,3,5-triene derivatives. Simple benzannulation involving the alkyne functionality of the propargylsilane does not appear to be a competitive reaction pathway in most cases.

The reaction of propargylsilanes with Fischer carbene complexes has been examined. If the silane-containing carbon is secondary the predominant pathway involves formation of conjugated dienes through a 1,2-silicon shift process of the initially formed vinyl-carbene complex intermediate. If a primary propargylsilane is employed, the silicon does not shift and normal alkyne-Fischer carbene coupling processes are observed. The process is moderately stereoselective, resulting in the E enol ether and Z alkenylsilane. (C) 2004 Elsevier B.V. All rights reserved.
