Abstract

1, 3-Dipolar cycloaddition of diazomethane to substituted 2-X-3-(2-furyl) acrylonitriles and the dependence of its course on the molar ratio of components was studied. The reaction takes place exclusively at the double bond under formation of 1-pyrazolines the further fate of which is determin~ d by the nature of the substituent X (X= CN, COOCH3, 4-N02 C6 H4) and by the reaction temperature.
