Abstract Addition of HCN to vinyltriethoxysilane, vinylmethyldiethoxysilane, vinyldimethylethoxysilane and 1, 3-divinyltetramethyldisiloxane affords the corresponding (cyanoethyl) silane in each case. The additions are catalyzed by tetrakis (triphenylphosphite) palladium (0) and give yields in the range 30–80%. In each of the palladiumcatalyzed reactions, the (2-cyanoethyl) silane isomer is the major addition ...
