Regio- and Stereoselective Homodimerization of Monosubstituted Acetylenes in the Presence of the Second Generation Grubbs Catalyst
Silyl- and phenylacetylenes undergo efficient homodimerization in the presence of a second generation Grubbs catalyst. The reaction permits fully regio- and stereoselective synthesis of disubstituted 1,3-enynes. The other commonly used ruthenium-based olefin metathesis catalysts remain inactive in the reaction.
