A facile oxidative cleavage of cyclic 1,2-diketones 1 to dicarboxylic acids 3 with hydroperoxide generated in situ has been developed. In situ generation of hydroperoxide was effected by the oxidation of 4,4′-dichlorobenzhydrol 2f to 4,4′-dichlorobenzophenone 4f using sodium hydride under oxygen atmosphere.
已经开发了用现场产生的氢过氧化物容易地将环状1,2-二酮1氧化为二羧酸3的方法。通过在氧气气氛下使用氢化钠将4,4'-二氯苯甲酸2f氧化为4,4'-二氯二苯甲酮4f进行氢过氧化物的原位生成。
