Let the sunshine in! Unactivated alkyl and aryl bromides underwent a light‐enabled reductive radical cyclization in the presence of a dimeric phosphine–gold complex as a photocatalyst (see scheme; X=C(CO2Et)2, NR, O). Sunlight can be used as the energy source for this simple and efficient radical reaction, which does not require potentially hazardous and toxic chemical reagents, such as organostannanes
让阳光照进来!未活化的烷基和芳基溴化物在二聚膦-金络合物作为光催化剂的情况下进行了光活化的还原性自由基环化反应(见方案; X = C(CO 2 Et)2,NR,O)。阳光可以用作此简单有效的自由基反应的能源,该自由基反应不需要潜在危险和有毒的化学试剂,例如有机锡和化学引发剂。
