Nouvelles Méthodes De Déshalogénation Et De Formation D'Alkyltriméthyl‐Acétals De Cétène Par Action De iPr₂NLi Sur Quelques α‐Bromoesters

Abstract

A previously described method consisting in reacting LDA with u-bromoketones has been ertended t o u-bromoesters. DeshaZogemtion ( a f t e r hydrolysis) and f o n a t i o n of ketene alkyZtrimethyZsiZyZ acetaZ8 ( a f t e r SiMejCZ addition) occur and show the genemZity of the method.
