Facile decarbonylation of the 4-formyl group in 5-alkyl amino pyrazoles was seen when reacted with catalytic p-toluene sulfonic acid in methanol under microwave irradiation to provide parent 4-H pyrazoles in good yields.

A series of 1-dialkylmino-1-butyn-3-ones were obtained, and their reactions with hydrazine and its alkyl, aryl and unsymmetrical dialkyl derivatives were studied.The reactions with unsubstituted and monosubstituted hydrazones lead to the formation of heterocyclic compounds of the pyrazole series, while the monosubstituted hydrazines form two isomeric products.Unsymmetrical dimethylhydrazine adds at the C1-carbon atom with the formation of compounds containing an open structure.
