The photochemical processes of N-propyl-o-sulfobenzoic imide to the amides were investigated in ethanol and monocyclic aromatics, such as benzene, anisole, toluene, polymethylbenzenes, and benzonitrile. It was clarified that although both the S1 and T1 states took part in those photochemical reactions, the mechanisms were different in ethanol and those aromatics. The mechanism in ethanol is thought
在乙醇和单环芳烃(如苯、苯甲醚、甲苯、多甲基苯和苄腈)中研究了 N-丙基-邻磺基苯甲酰亚胺到酰胺的光化学过程。澄清了尽管 S1 和 T1 状态都参与了这些光化学反应,但乙醇和那些芳烃的机制不同。乙醇中的机制被认为涉及通过二氧化硫挤出后形成的双自由基从乙醇中提取氢原子。芳烃的机理涉及能量从单线态激发的芳烃分子转移到磺基苯甲酰亚胺,以及将得到的双自由基添加到伙伴芳烃中。尽管苯中的苯乙酮使磺基苯甲酰亚胺敏化为三线态,但也导致了芳基化苯甲酰胺的形成,与通过 S1 状态的过程相比,这个过程是次要的。这归因于双自由基的三重多重性。苏...
