Visible‐Light‐Induced Bromination of α‐Diazo Compounds with Bromoform

Abstract An efficient visible‐light‐driven strategy for bromination of α ‐diazo compounds is achieved for the construction of α‐bromoesters with bromoform. It is noteworthy that the reaction occurs under sole light irradiation without a photocatalyst or an additive. Several synthetic transformations and gram‐scale reactions demonstrate the synthetic potential of this photochemical reaction.
