A compound having a first ligand of the following is described. Ring A represents a monocyclic aromatic group or a polycyclic aromatic group. Ring B represents a polycyclic aromatic group. Z is a carbon. Z and the right N are coordinated to a metal to form a five-membered chelate ring. R1 and R2 independently represent mono to a maximum possible number of substitutions, or no substitution.

Copper-catalyzed cross-coupling reactions of amidine salts were utilized to synthesize monoarylated amidines in moderate to high yields with ligand-free conditions. DMF was the superior solvent for the N-arylation of benzamidines, while MeCN was used in the formation of N-aryl amidines in moderate to high yield.(Figure Presented)
