The present invention relates to a process for the oxidation, in an inert solvent, of a non-aromatic or non-enonic ethylenic bond or of a non-conjugated cyclic ketones into the corresponding epoxides, respectively lactone, using H?2#191O?2#191 as oxidant, a content in water of the reaction medium below 15% w/w and, as sole catalyst, an alkaline or alkaline earth salt or complex.
本发明涉及一种在惰性溶剂中将非芳香性或非环烯基键氧化为相应环氧化物或将非共轭环酮氧化为相应内酯的过程,使用H?2#191O?2#191作为氧化剂,反应介质中的水含量低于15%(质量百分比),唯一催化剂为碱性或碱土金属盐或络合物。
