title: Nickel-catalyzed highly regio- and stereoselective cross-trimerization between triisopropylsilylacetylene and internal alkynes leading to 1,3-diene-5-ynes.
abstract: The first highly selective 1:2 cross-trimerization between triisopropylsilylacetylene and 2 equiv of internal alkynes, leading to 1,3-diene-5-yne compounds, was achieved using the Ni(cod)(2)/P(n)Pr(3) catalyst. Various symmetrical and asymmetrical internal alkynes could be used for the cross-trimerization reaction with high regio- and stereoselectivity.
