Addition of the silicon-boron bonds of (dimethylphenylsilyl)boranes having pinacol, catechol, and diethylamino groups on the boron across carbon- carbon triple bonds is effectively catalyzed by palladium complexes. The silaboration of a variety of terminal alkynes took place with almost complete regio- and stereoselectivity to afford (Z)-1-boryl-2-silylalkenes in high yields. The silaboration products were subjected to the palladium-catalyzed cross-coupling reaction with aryl iodide and rhodium-catalyzed conjugate addition to methyl vinyl ketone, giving β-silylstyrene derivatives and δ- silyl-γ,δ-unsaturated ketones, respectively, in high yields.

The first example of gold-catalyzed silaboration of alkynes with PhMe 2SiBpin is documented in the presence of supported gold nanoparticles. In the case of terminal alkynes, the reaction proceeds at ambient conditions in very good yields and th

Addition of the silicon-boron bond across carbon-carbon triple bonds, i.e. silaboration is most effectively catalysed by a palladium(0)-tert-alkyl isocyanide complex to give (Z)-1-boryl-2-silyl alkenes with high regio- and stereo-selectivity, which are useful for synthesis of stereodefined alkenylsilanes.
