A photo opportunity: A visible‐light‐excited iridium catalyst delivers electrons from an amine to an organohalide. The electron transfer then induces reductive scission of the carbon–halogen bond, generating the corresponding alkyl, alkenyl, and aryl radical that can undergo cyclization and hydrodehalogenation reactions.

铱催化剂将电子从胺传递到有机卤化物。然后,电子转移引起碳-卤素键的还原断裂,产生相应的烷基,烯基和芳基,这些基团可能会发生环化和加氢脱卤反应。
