method for the generation of acyl and phosphoryl radicals from formamides, aldehydes, and phosphine oxides has been developed. This protocol utilizes 9,10-phenanthrenequinone (PQ) as both a molecular catalyst and a hydrogen atom-transfer (HAT) reagent, eliminating the requirement for external metal-based reagents, HAT reagents, and oxidants. The generated acyl radicals can be applied to a range of
开发了一种有机催化光电化学方法,用于从甲酰胺、醛和氧化膦产生酰基和磷酰基自由基。该方案利用 9,10-菲醌 (PQ) 作为分子催化剂和氢原子转移 (HAT) 试剂,无需外部金属试剂、HAT 试剂和氧化剂。生成的酰基自由基可应用于一系列自由基介导的转化反应,包括杂芳烃的C-H氨基甲酰化、CF 3取代的N-芳基丙烯酰胺的分子间串联自由基环化以及分子内环化反应。在这些转化中使用酰基自由基为获取结构多样的羰基化合物提供了一种有效且可持续的方法。
