A novel, convenient and efficient protocol for the construction of various 2-aminophenyl benzothiazoles by domino intra- and intermolecular C–N cross-coupling reactions of arylisothioureas with aryl iodides using an inexpensive, air stable and readily available copper catalyst is described. The arylisothioureas were obtained from thiourea via copper promoted desulfurization followed by nucleophilic
Abstract A simple route for the synthesis of 2-aminophenyl benzothiazole through domino intra and inter molecular C-N cross-coupling reaction using a cobalt catalyst under mild reaction conditions has been accomplished. The procedure is experimentally simple, general, and efficient. All the substrates readily carried out under optimized reaction conditions to provide target products in moderate to
