Palladium-catalysed addition of the silicon–tin bond to alk-1-ynes and 1,1-dimethylallene
Abstract
(Trimethylsily)trimethylstannane adds regio- and stereo-specifically to alk-1-ynes in the presence of tetrakis(triphenylphosphine)palladium(0); regiospecific addition to 1,1-dimethylallene is also observed.
