Production of the triarylamine

PROBLEM TO BE SOLVED: To provide a method for producing a triarylamine compound by coupling an N, N-dialkyl sulfamate compound and a diaryl amide compound in the presence of a nickel catalyst.SOLUTION: A triarylamine is produced by allowing an N, N-dialkyl sulfamate represented by formula (1) (in the formula, Arrepresents a phenyl group or the like, and Rand Reach independently represents a 1-4C alkyl group that may be substituted with a fluorine atom) to react with a diarylamide in the presence of a nickel catalyst.

Ni-catalyzed arylation of bromomagnesium diarylamides with aryl N,N-dimethylsulfamates

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.
