Alkynylsilanes are an important class of organic compounds and dehydrogenative coupling of hydrosilanes with terminal alkynes provides a convenient and simple route to alkynylsilanes. On the other hand, calcium is an abundant, biocompatible, and environmentally friendly element and using organocalcium complexes as catalytic reagents in organic synthesis recently attracted increasing attentions. Here we report an organocalcium complex-catalyzed dehydrogenative coupling of hydrosilanes with terminal alkynes. With a calcium alkyl complex [LCaCH2SiMe3] (L=[MeC(NDipp)CHC(tBu)NCH2CH2N(Me)CH2CH2NMe2]?, Dipp=2,6-(iPr)2C6H3) as the catalyst, the reactions of n-HexSiH3 with terminal alkynes provide trialkynylsilanes and those of Et2SiH2 with terminal alkynes give monoalkynylsilanes efficiently.

In the presence of an amine, copper(I) chloride is an effective catalyst for the cross-dehydrocoupling of silanes with alkynes.The reactions proceed at useful rates above 100 deg C, but rates drop dramatically on going from 1o to 2o
