A fundamental quest for alkyl radical generation under mild conditions through photoinduced Brønsted acid catalysis is addressed. The optimized protocol does not require any organic dyes or transition metal photocatalyst. Under blue light irradiation with diphenyl phosphate as a catalyst and dihydropyridine derivatives as a radical source, functionalized arylmethane derivatives are obtained in high yield.
本文探讨了通过光致布朗斯特酸催化在温和条件下生成烷基自由基的基本问题。优化后的方案不需要任何有机染料或过渡金属光催化剂。以二苯基磷酸酯为催化剂、二氢吡啶衍生物为自由基源，在蓝光照射下，可高产率地得到官能化芳基甲烷衍生物。
