CONVERSION OF DISILANES TO FUNCTIONAL MONOSILANES. XII. THE PALLADIUM(0)-CATALYZED DECHLORINATIVE SILYLATION OF BENZYLIC CHLORIDES WITH METHYLCHLORODISILANES. A FACILE ROUTE TO BENZYLMETHYLCHLOROSILANES
This paper describes the facile dechlorinative silylation of benzylic chlorides of types XC6H4CH2Cl (X = H, Me and Cl) and ClCH2C6H4CH2Cl (o-, m- and p-isomers) with methylchlorodisilanes ClMe2SiSiMe2Cl, ClMe2SiSiMeCl2 and Cl2MeSiSiMeCl2 in the presence of Pd(PPh3)4 to give the corresponding benzylmethylchlorosilanes in good to high yields.
A CONVENIENT SYNTHESIS OF BENZYLMETHYLCHLOROSILANES BY THE PALLADIUM-CATALYZED DECHLORINATIVE SILYLATION OF BENZYLIC CHLORIDES WITH METHYLCHLORODISILANES
Benzylmethylchlorosilanes were prepared in high yields by the dechlorinative silylation of benzylic chlorides with methylchlorodisilanes MenSi2CI6-n (n = 2, 3, and 4) in the presence of a catalytic amount of Pd(PPh3)4.
