Abstract

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.
