have been studied. More than half of the 2-phenoxyprop-2-yl radicals thus produced thermally cause the phenyl group to migrate from oxygen to the carbon, followed by elimination of the methyl group. Most of the remaining radicals abstract hydrogen from the solvent. When phenyl ether is employed as a solvent, homolytic aromatic substitution takes place yielding isopropylbenzene derivatives. It is shown
已经研究了偶氮双(2-苯氧基)-2-丙烷的热分解和光解。由此产生的超过一半的 2-苯氧基丙-2-基自由基通过热导致苯基从氧迁移到碳,然后消除甲基。大多数剩余的自由基从溶剂中提取氢。当苯醚用作溶剂时,发生均裂芳族取代产生异丙苯衍生物。尽管不是完全决定性的,但从机理上的考虑表明,这是一种新型反应,因为一部分离去基团构成了一部分进入基团。
