Simple and Convenient Methods for N-Arylation of Heterocycles and Diphenylamine

Abstract

N-Arylation of NH-heterocycles and diphenylamine with various aryl halides, using a readily accessible ligand-free potassium tert-butoxide/iron(III) oxide/dimethyl sulfoxide reagent system, gives the corresponding N-aryl derivatives in 47–97% yields.

Key words

iron(III) oxide - N-aryl heterocycles - N-arylimidazole - triarylamines
