Palladium-catalyzed silylation of allylic acetates with hexamethyldisilane or (trimethylsilyl)tributylstannane
1993
Various allylic acetates (1a-j) are silylated with hexamethyldisilane (Me 3 SiSiMe 3 , 2) in the presence of a catalytic amount of Pd(DBA) 2 and LiCl at 100 o C to afford the corresponding allylic silanes in high yields. In addition, (trimethylsilyl)tributylstannane (Me 3 SiSnBu 3 , 3) can be used for the silylation of aromatic allylic acetates 1g-j at room temperature
