3-Diazopyrazolo[3,4-c]pyridazine was synthesized and its transformations were investigated. With reactive methylene compounds the corresponding hydrazones and condensed 1,2,4-triazines were formed. With aromatic amines and naphthols the diazo compound was converted into arylazo derivatives. The diazo compound underwent cycloaddition, reacting as a 1,4-dipole to yield cycloaddition products.
