    Iron‐Catalyzed Intermolecular Azidabenzoyl Difluoromethylation of Alkenes to Access β ‐Difluoroacyl Azides
    摘要:
    AbstractA Fe(II)‐catalyzed three‐component reaction of 2‐iodo‐2,2‐difluoroacetophenones, alkenes and TMSN3 is described, which provides a particularly valuable route to access difluoroalkylated azides with high yields. The method permits the efficient azidation of varied β‐difluoroacyl‐benzylic radicals in mild conditions with high functional group tolerance. Preliminary mechanistic investigation indicated that a radical‐mediated process was involved in this azidadifluoroacylation reaction.
