Transition metal-catalyzed process for preparing N-aryl compounds

Abstract

The present invention is directed to a process for the preparation of N-aryl compounds containing at least one unsaturated nitrogen atom, comprising reacting a compound having at least one unsaturated nitrogen atom with an arylating compound in the presence of a base and a transition metal catalyst under reaction conditions effective to form an N-aryl compound containing at least one unsaturated nitrogen atom, wherein the aryl moiety of the N-aryl compound is bonded to the at least one unsaturated nitrogen atom, the transition metal catalyst comprising a Group 8 metal and at least one chelating ligand selected from the group consisting of Group 15-substituted metallocenes, Group 15-substituted arylenes, unsaturated Group 15 heterocycles, Group 15-substituted alkanes, and combinations thereof. The process of the present invention a useful general method of N-arylation for the manufacture of pharmaceuticals, polymers, and the like.
