ABSTRACT
A variety of new pyrazole, pyrrolinopyrazole and pyrazolopyridazine derivatives were synthesised via the dipolar cycloaddition reactions of acrylonitrile, ethyl acrylate and N-arylmaleimides with the nitrile imine regenerated from 2-bromo-1- benzofurylglyoxal-2-[3-phenylpyrazol-5-yl]-hydrazone. Structure of the newly synthesized derivatives were established on the basis of elemental analysis and spectral data
