Michael Addition of Ylidenpyrazolones

The reactivity of ylidenpyrazolones (1a-c) towards compounds bearing an activated double bond has been investigated.Ia on treatment with acrylonitrile furnishes the amide (II) while with ethyl acrylate, N-arylmaleimides and dimethyl acetylendicarboxylate, the Michael adducts (IV-VI) are obtained.The reaction of Ib and Ic with acrylonitrile and ethyl acetate gives the adducts VII.
