simple and efficient procedure for the synthesis of N-[(methylthio)methyl]benzamides and methylene-bridged unsymmetrical bisamides was achieved mediated by DMSO in the presence of acetic acid. DMSO plays a dual role in the transformation, as not only a solvent, but also an environmentally benign methylene source. The protocol provides new strategies for effective synthesis of unsymmetrical bisamides
