The photochemical decomposition of the title compounds yielded the rearrangement products derived from 1,3- and 1,5-aroyloxyl migrations in addition to the fragmentation products typical of the aroyloxyl and amido radicals, while only 1,3-aroyloxyl migration was observed on thermolysis. The results of crossover experiments indicate an intramolecular rearrangement, probably involving homolysis of the
标题化合物的光化学分解产生了源自 1,3- 和 1,5- 芳酰氧基迁移的重排产物以及典型的芳酰氧基和酰氨基自由基的断裂产物,而在热解过程中仅观察到 1,3- 芳酰氧基迁移. 交叉实验的结果表明分子内重排,可能涉及激发态 N-O 键的均裂。三重态猝灭研究表明,重排和碎裂仅通过第一激发单重态进行。基于对溶剂笼内自由基-自由基复合过程的自旋多重效应,没有解释三线态敏化时重排产物的形成。
