Visible Light‐Promoted Three‐Component Carboazidation of Unactivated Alkenes with TMSN3 and Acrylonitrile

Abstract A novel difunctionalization of unactivated alkenes has been reported via visible light‐promoted three‐component carboazidation using TMSN 3 and acrylonitrile as partners without any stoichiometric oxidants. This protocol is operationally simple for straightforward access to azido derivatives with good functional group tolerance from readily available starting materials. A facile azido radical‐catalyzed [3 + 2] cycloaddition reaction of vinylcyclopropane with acrylonitrile was also observed to deliver a multi‐substituted cyclopentane.
