Under microwave irradiation vinylpyrazoles react with ethyl N-trichloroethylidenecarbamate1 to give the addition to the imine system through the conjugated vinyl group. Likewise, compound 1 react with the NH group of pyrazolylhydrazones, if present. To the best of our knowledge this reaction type has not been described before and only can be performed under microwave irradiation. By classical heating
