1,3,2-diazaphospholenes hydrides (DAP-H) are shown as efficient catalysts for reductive radical cyclization of aryl and alkyl halides under irradiation with visible light. The pivotal DAP catalyst turnover was achieved by a DBU-assisted σ-bond metathesis between the formed DAP halide and HBpin.
1,3,2-二氮杂磷烯氢化物 (DAP-H) 被证明是可见光照射下芳基卤化物和烷基卤化物还原自由基环化的有效催化剂。关键的 DAP 催化剂周转是通过 DBU 辅助形成的 DAP 卤化物和 HBpin 之间的σ键复分解实现的。
