Abstract
A visible‐light‐induced photoredox‐catalyzed radical tandem cyclization of o‐isocyanodiaryl amines with arylthiodifluoroalkyl 2‐pyridyl sulfones or difluormethyl bromides has been realized for the first time. The reaction works with a broad range of substrates and provides a simple and efficient method for the synthesis of 11‐difluoromethyl‐substituted dibenzodiazepines from easily available starting materials in very mild conditions.
