The present invention relates to a method for manufacturing an ester from a ketone or an aldehyde, which is a reactive substrate, by a Baeyer-Villiger oxidation reaction using hydrogen peroxide, and in this method, as a catalyst, M(BAr4)n, which is a metal borate, is used (M represents an alkali metal or an alkaline earth metal; Ar represents an aryl; and n is the same number as the valence of M). For example, when cyclohexanone was used as the reactive substrate, and Sr[B(3,5-CF3C6H3)4]2 was used as the catalyst, ε-caprolactone was obtained at an isolated yield of 82%.
本发明涉及一种用过氧化氢通过拜耳-维利格氧化反应从酮或醛制取酯的方法,酮或醛是反应性底物,在该方法中,作为催化剂,使用金属硼酸盐M(BAr4)n(M代表碱金属或碱土金属;Ar代表芳基;n与M的价数相同)。例如,以环己酮为反应底物,Sr[B(3,5-CF3C6H3)4]2 为催化剂,可得到ε-己内酯,分离产率为 82%。
