在此,我们报告了光激发硝基芳烃促进醇、胺、醛和亚胺厌氧氧化的方案。机理研究支持光激发硝基芳烃与醇和胺经历双氢原子转移(HAT)步骤以提供各自的酮和亚胺产物的观点。在醛和亚胺存在的情况下,连续发生 HAT 和氧原子转移 (OAT) 事件,分别产生羧酸和酰胺。这种转变适用于连续光流设置,从而缩短了反应时间。

The reaction of polychloroiodoarenes with copper in dimethylformamide gives good yields of the biaryls. 4Bromotetrachloropyridine gives products of halogen exchange and reduction as well as coupling. Pentachloropyridine gave only tetrachloropyridines. Evidence against free radical or pyridyne intermediates is presented, and it is postulated that the reactions proceed via pyridylcopper compounds, although
