Broad in scope: The first amination of arylsulfamates, which are attractive cross‐coupling partners, particularly for multistep syntheses, was achieved by using a nickel catalyst. The method provides a versatile means to use simple derivatives of phenol as precursors to polysubstituted aryl amines, as exemplified by a concise synthesis of the antibacterial drug linezolid (see scheme).

often chosen for transitionmetalcatalyzed C-N coupling reactions. In this work, it was found that the use of alkane solvents (e.g. cyclohexane, heptane) allows for highly efficient Ni-catalyzed C-N coupling of aryl pseudohalides with different types of amines in the presence of NHC ligands. Excellent functional group tolerance was achieved. Stronger hydrogen bonding effect between amine NH moiety
