Reaction of antipyrine with Schiff bases

New dihydropyrazolone derivatives were prepared by condensation of antipyrine with substituted arylmethyleneanilines or arylmethylene-2- naphthylamines. Pleiades Publishing, Inc., 2006.

Solvent-free condensation of aromatic aldehydes and 2,3-dimethyl-1-phenyl-3-pyrazolin-5-one by p-toluenesulfonic acid

Solvent-free condensation easily occurred by mixing aromatic aldehydes and 2,3-dimethyl-1-phenyl-3-pyrazoline-5-one (antipyrine) in the presence of p-toluenesulfonic acid as a solid acid catalyst at room temperature to give the corresponding disubstituted

Co-condensation of 2-Aminopyridine, Aromatic Aldehydes, and Ketones

The co-condensation of 2-aminopyridine with aromatic aldehydes and ketones proceeds via the initial formation from the amine and the benzaldehydes of (2-pyridylamino)aryl carbinols, which then react with p-nitroacetophenone to give 3-aryl-1-(4-nitrophenyl

REACTION OF SCHIFF BASES OBTAINED FROM 4-AMINOANTIPYRINE AND 4-AMINO-1,2,4-TRIAZOLE WITH KETONES

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.
