ETHYL (DIPHENYLMETHYLSILYL)ACETATE

ETHYL (DIPHENYLMETHYLSILYL)ACETATE 화학적 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.
