We have developed visible-light photoredox decarboxylative couplings of N-(acetoxy)phthalimides without an added photocatalyst in which simple and commercially available thiophenols are used as the effective organocatalysts, and 4-(trifluoromethyl)thiophenol shows optimal catalytic activity. Three representative decarboxylative examples were chosen including one amination and two C–C bond couplings
我们已经开发了在不添加光催化剂的情况下N-(乙酰氧基)邻苯二甲酰亚胺的可见光光氧化还原脱羧偶合,其中简单的和可商购的苯酚被用作有效的有机催化剂,而4-(三氟甲基)苯硫酚显示出最佳的催化活性。选择了三个代表性的脱羧实例,包括一个氨基化和两个C–C键偶联,以确认可见光氧化还原反应的功效,结果表明它们在室温下表现良好。有趣的发现应该为有机分子的可见光光氧化还原转化提供一种新颖且环保的策略。
