A novel synthetic methodology was developed for the N-arylation of nitroenamine derivatives utilizing diaryliodonium triflates and copper (I) chloride as a catalyst. The procedure enables the ease aryl transfer from the hypervalent species under mild catalytic conditions with unusual heteroatom preference and high efficiency.
