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.
