The combination use of Ni(cod)2 and N,N-1,3-bis(2,6- diisopropylphenyl)-4-imidazoline-2-ylidene as a catalyst successfully gave unsymmetrical N,N-diaryl-N′,N′-diphenyl-1,1′-biphenyl-4, 4′-diamines through the arylation of bromomagnesium diarylamide with 1-(4′-diphenylamino-1,1′-biphenylyl) N,N-dimethylsulfamate. This Ni catalyst and Grignard reagents of diaryl or monoarylamides were also useful in the syntheses of various triarylamines and diarylamines from corresponding aryl N,N-dimethylsulfamates. 2012 Elsevier Ltd.
