t-Butyl (Methyldiphenylsilyl)acetate C화학적 특성, 용도, 생산
물리적 성질
clear to light yellow liquids.
용도
vinyl 1,1-dication synthetic equivalent in reactions with
Grignard reagents; reagent for Peterson synthesis of α,β-un
saturated esters.
제조 방법
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.
