Convergent synthesis of triarylamines via Ni-catalyzed dual C(sp2)–H amination from benzamides with benzohydroxamic acids

Abstract

An unprecedented method of nickel-catalyzed dual C(sp2)–H amination of N-quinolylbenzamides with benzohydroxamic acids is developed to access triarylamines in one pot. For the first time, broad-spectrum hydroxylamine is employed as an amino source for C–H amination, featuring good chemo-selectivity and functional group tolerance. Furthermore, the catalytic system could be further extended to N-(pivaloyloxy)benzamide, dioxazolone, isocyanate and aniline for C–H amination.
