Abstract

original image

Unaktivierte Alkyl- und Arylbromide gehen eine reduktive radikalische Cyclisierung in Gegenwart eines dimeren Phosphan-Gold-Komplexes als Photokatalysator ein (siehe Schema; X=C(CO2Et)2, NR, O). Sonnenlicht kann als Energiequelle für diese einfache und effiziente Radikalreaktion genutzt werden, wodurch sich potenziell gefährliche und toxische chemische Reagentien wie Organostannane und chemische Initiatoren vermeiden lassen.
