P2S5 in methylene chloride containing pyridine reduces allenyl phenyl sulphoxides to sulphides; the difficult hydrolysis of the latter is eased by the introduction of a methoxy group into the benzene ring and this method then becomes a practicable synthesis of αβ-unsaturated ketones.
含吡啶的二氯甲烷中的P 2 S 5将烯丙基苯基亚砜还原为硫化物;后者的水解难以通过引入甲氧基的成苯环缓和,则此方法变得α的切实可行合成β不饱和酮。
