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.
