Abstract

The two-component condensation of 2-chloro- or 2-bromo-N-ethoxycarbonylmethylpyridinium halides and aryl- or hetarylmethylidenemalononitriles gave ethyl 2-[2-(dicyanomethylidene)pyridin-1(2H)-yl]-3-arylacrylates. Correlation NMR spectroscopy and X-ray diffraction structural analysis allowed the structural characterization of these products.
