Palladium-catalysed addition of trimethylsilyl cyanide to arylacetylenes
Abstract
The reaction of arylacetylenes with trimethylsilyl cyanide (1)in the presence of a palladium complex resulted in addition of (1) across the carbon–carbon triple bond with high regio- and stereo-selectivity to give β-cyano-β-arylalkenylsilanes.
