presented as an efficient method for synthesis of 2-(arylamino)aryliminophosphoranes, useful as starting materials in the synthesis of benzannulated nitrogen heterocycles. The reaction is complementary for the known synthesis of aryliminophosphoranes from2-nitrosodiarylamines giving rise to obtain the title products in the broader scope. The presented protocol is simple and efficient although limited to

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 CS bond formation, associated with CS bond breakage, followed
