Allyltrimethylsilane reacted with various nitriles in the presence of borontrichloride, giving after hydrolysis β,γ-unsaturated ketones in high yields. The reactions of substituted allyltrimethylsilanes and intramolecular reaction of allylic trimethylsilane with nitrile were also studied.
Cationicnitrileplatinum(II) complexes of formula [PtMe(RCN)(bipy)]+ undergo nucleophilic addition of carbanions −CH(COX)(COY) (X, Y= Me, OMe), −CH(CO2Me)CN and −CH(CN)2 to afford neutral products. According to the nature of the nucleophile, the organic ligand fragment displays either an imino enol or an enamine isomeric structure. The Pt−N bond can be cleaved upon reaction with acids with formation
