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.
