The Uses of Silane, trimethyl[1-[(trimethylsilyl)oxy]-2-propen-1-yl]-

3-Trimethylsilyl-3-trimethylsilyloxy-1- propene is used in homoenolate anion and homoenolate dianion equivalents; synthesis of acylsilanes. It takes part in reactions of Homoenolate Anion Equivalent,Homoenolate Dianion Equivalent, Synthesis of Acylsilanes, etc.

Preparation

Allyl trimethylsilyl ether is lithiated with sbutyllithium in THF¨CHMPA to give a rapidly equilibrating mixture of a carbanion and a silylallyloxy anion (eq 1). Silylation of the mixture with chlorotrimethylsilane affords 3-trimethylsilyl- 3-trimethylsilyloxy-1-propene (1) exclusively. Several other derivatives with bulky substituent(s) on the silyloxy group were also prepared.
