Microwave-assisted synthesis of N,N '-disubstituted acetamidine Ligands

Under microwave activation, triethylorthoacetate reacts with the substituted anilines in the presence of acetic acid as a catalyst, producing acetamidine in moderate to high yields. The X-ray structures of the new amidines, N,N'-bis(3,5-dimethylphenyl)acetamidine and N,N'-bis(p-tolyl) acetamidine, are also reported, revealing polymeric chains supported by intramolecular H-bonds.
