The reductive ring-opening of hydroperoxides derived from cyclic ketones leads to alkyl radicals which can effectively be trapped by arenediazonium salts. This synthetic transformation yielding azo carboxylic acids or lactams, after a reductive step, can be classified as a radical version of the well-known Beckmann rearrangement. In this article, we present results on the scope, the limitations and
衍生自环状酮的氢过氧化物的还原性开环导致烷基自由基,该烷基自由基可被芳二氮杂鎓盐有效地捕获。在还原步骤之后,这种产生偶氮羧酸或内酰胺的合成转化可以归类为众所周知的贝克曼重排的自由基形式。在本文中,我们介绍了这种新型反应类型的范围,局限性和可能的应用结果。 自由基反应-重排-酮-羧酸-偶氮化合物
