With acetophenone and p-nitroacetophenone in alcohol and benzene media in the presence of acid N-arylidene-4-aminoantipyrines form α,β-unsaturated ketones, and with antipyrine the form aryldiantipyrylmethanes.With the same ketones N-arylidene-4-amino-1,2,4-triazoles form the products from addition at the azomethine bond.In both cases reaction with benzylideneacetone was not detected.
