Bromo Radical‐Mediated Photoredox Aldehyde Decarbonylation towards Transition‐Metal‐Free Hydroalkylation of Acrylamides at Room Temperature

Abstract Herein, we report a visible‐light‐mediated hydroalkylation reaction of alkenes using easily available aldehydes as alkyl sources via bromo radical‐promoted photoredox decarbonylation. This protocol provides an alternative entry to C( sp 3 )−C( sp 3 ) bond formation and features considerable advantages including mild and clean reaction conditions, obviation for transition‐metal catalyst, and good functional group compatibility. magnified image
