The dianion of the β-keto-sulphoxide (1) can be alkylated exclusively on the γ-carbon atom with a variety of alkyl halides; the resultant α-phenylsulphinyl ketones (3) undergo ready elimination of benzenesulphenic acid providing a new general route to alkyl vinyl ketones.
β-酮亚砜(1)的二价阴离子可以用多种烷基卤化物专门在γ-碳原子上烷基化;所得的α-苯基亚磺酰基酮(3)进行了苯磺酸的快速消除,为烷基乙烯基酮提供了一条新的通用路线。
