Palladium-catalysed methylation of diethyl phosphates derived from optically active γ-trimethylsilylallyl alcohols proceeds in a highly regio- and stereo-selective manner to give optically active vinylsilanes having an allylic methyl group.
Substitution of secondary allylic phosphates with the anions derived from Ar2CH2 with BuLi or LDA proceeded regioselectively and stereoselectively without a metal catalyst, affording inversion products in good yield. Similarly,...
