摘要：

Trimethylsilylacetylene was catalytically dimerized by Ru(cod)(cot)/PR3(cod=1,5-cyclooctadiene, cot=cyclooctatriene) to give either Me3SiCH=C=C=CHSiMe3 when PR3=PPh3 or (Z)- Me3SiCH=CH-C=CSiMe3 when PR3=PBu3n, the latter being formed by stereoselective isomerization of initially formed (Z)-Me3SiCH=C-C=CHSiMe3.
