Oxidation with m-chloroperbenzoic acid of the ethylene acetals of aryl α-phenylseleno-or aryl α-phenyltelluro-ethyl kitones prepared by treating the corresponding α-bromo compounds with diphenyl diselenide–sodium or diphenyl ditelluride–sodium, respectively, affords hydroxyethyl 2-arylpropanoates in moderate to good yields via aryl group migration.
氧化与米kitones的芳基α-phenylseleno -或芳基α-phenyltelluro乙基乙烯缩醛氯过苯甲酸制备通过用二苯基二硒化物,钠或二碲化物二苯基-钠相应的α溴代化合物,分别得到2-羟乙基芳基丙酸酯通过芳基基团迁移以中等至良好的收率。
