✦ Synopsis

Acylation of E-phosphoranium salts with E-acyl chlorides gives the corresponding Z-perfluoro betaine in high yield.

Subsequent chlorination or bromination regiospecifically yields the a,d-dihalofluoromethyl perfluoroalkyl ketones.

AbstractÐA convenient synthesis of a-diones and their monoprotected acetals, i.e. a-ketoacetals, was developed by mercury induced solvolysis of regiospeci®cally formed a-chloro-a-(alkylthio)ketones. Analogously, a-alkoxy-a-sulfenylated ketones were formed when reacting a-chloro-a-sulfenylated ketone
