Room Temperature Cu-Catalyzed N -Arylation of Oxazolidinones and Amides with (Hetero)Aryl Iodides.

N , N '-Bis(pyridin-2-ylmethyl)oxalamide (BPMO) was found to be an apposite promoter for the Cu-catalyzed N -arylation of oxazolidinones and primary and secondary amides with (hetero)aryl iodides at room temperature. Excellent chemoselectivity reached between aryl iodides and aryl bromides, and a wide range of functional groups tolerated the reaction conditions, which led to the formation of greatly diverse N -arylation products.
