Abstract We have developed a ligand-assisted copper (I)-catalyzed two sequential heteroarylation sequence. An intramolecular S-arylation is followed by an intermolecular N- arylation leading to the direct synthesis of N-aryl-2-aminobenzothiazoles. In most cases however, the 2-arylsulfanyl-arylcyanamide was the major product obtained via an intramolecular C [BOND] S bond formation, associated with C [BOND] S bond breakage, ...
