Substituted Hantzsch esters can act as radical reservoirs in photoredox reactions, steadily releasing a carbon radical and a hydrogen atom radical in the absence of an additional electron acceptor. We propose that radical release by substituted Hantzsch esters occurs via a mechanism involving an internal redox cycle. Cinnamidecinnamides, styrenes, α,β‐unsaturated acids, and diarylethenes could be alkylated smoothly with these reagents.

取代Hantzsch酯作为光氧化还原反应中的多用途自由基贮库

取代的Hantzsch酯可在光氧化还原反应中充当自由基储存库，在不存在其他电子受体的情况下稳定释放碳自由基和氢原子自由基。我们建议，通过涉及内部氧化还原循环的机制，发生由取代的汉茨（Hantschsch）酯释放的自由基。肉桂酰胺，苯乙烯，α，β-不饱和酸和二芳烃可以用这些试剂平稳地烷基化。
