| | t-Butyl (Methyldiphenylsilyl)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. |
