Abstract

The reaction of PhCOCH 2 Br and NaOMe in MeOH gave PhCOCH 2 OH as the major product and PhCOCH 2 OMe as the minor product. Substituent effects on the reactivity and product selectivity revealed that an electron-withdrawing substituent on the phenyl ring enhanced the overall reactivity and gave more alcohol than ether. It was indicated that the alcohol was formed via carbonyl addition-epoxidation, whereas the ether was formed by ...
