Cyanoacetohydrazide 1a reacts with 2-arylhydrazoketons 2a,b and 3a,b in refluxing ethanol to yield pyrido[5′,4′:2,3][1,3,4]oxadiazolo[3,2-a]pyridine and pyridazine derivatives; in the absence of solvent pyrazolo[1,5-a]pyrimidine derivatives were obtained.

A novel series of 1-(substituted)-3,5-dimethyl-2-(arylazo) pyrazoles (3a-l) was synthesized by reacting various 1,3-diketo-1,3-dimethyl-2-(arylazo) propanes (2a-l), with benzohydrazide in acidic medium 2a-l. 2a-l were prepared by diazotization of appropri
