ETHYL (DIPHENYLMETHYLSILYL)ACETATE Usage And Synthesis
Physical properties
clear to light yellow liquids.
Uses
vinyl 1,1-dication synthetic equivalent in reactions with Grignard reagents; reagent for Peterson synthesis of α,β-un saturated esters.
Preparation
whereas the direct silylation of the lithium enolate of an ester normally results in the formation of a mixture of the α-silyl ester and the corresponding silyl ketene acetal, the same reaction with methyldiphenylchlorosilane gives exclusively the α-methyldiphenylsilyl ester. This direct C-silylation is the best general route to α-silyl esters.
