Oligomerization of trimethylsilylacetylene in the presence of catalytic systems based on group III–VI transition metal halides

The features of the reaction of oligomerization of trimethylsilylacetylene in the presence of group III–VI transition metal compounds combined with triisobutylaluminum were investigated. The effect of the nature of the transition metal, cocatalyst, and conditions of conducting the oligomerization reaction on the yield and composition of the products of the reaction were studied. It was shown that it is possible to obtain either linear products of oligomerization or the cyclic trimer, or a mixture of both by varying the nature of the catalyst.Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 12, pp. 2823–2828, December, 1989.
