achieved using benzoyl hydrazides as an efficient acyl source undermild reaction conditions. The photo-redox catalyzed oxidative cleavage of hydrazides leads to in situ formation of acyl radicals, which subsequently couple with various N-heterocycles to produce acylated products. This synthetic strategy performs the classic Minisci reaction in an eco-friendly and greener way with functional group tolerance
photoinduced acylation of N‐heterocycles is explored. This visible‐lighttriggered reaction occurs not only under extremely mild reaction conditions, but also does not require the presence of a photosensitizer. The mechanistic studies suggest formation of EDA complexes prompt to harness the energy from visible‐light. Compatibility with a large panel of α‐keto acids as acyl precursors and an array of N‐heterocycles
