摘要

A new method to effect the direct C-silylation of ketones is proposed by reaction with the Me 3 SiCl/Li/THF system. With saturated ketones or with α-ethylenic ketones in which the sequence is not conjugated with another group, direct C-silylation has been carried out for the first time. Under mild conditions (0–10°C), the reaction occurs with good yields. Various new compounds have been synthetized; ketones β-silylated with respect to tile carbonyl group, α-silylated ...
