Abstract
6-Aryl-2-(dicyanomethylidene)-4-oxo-3-azabicyclo[3.1.0]hexane-1,5-dicarbonitriles were synthesized by treatment of 2-amino-6-aryl-4-(dicyanomethylidene)-3-azabicyclo[3.1.0]hex-2-ene-1,5-dicarbonitriles with a solution of sulfuric acid in acetic acid. The reaction with aqueous sulfuric acid gave 1-(1-amino-2,2-dicyanovinyl)-3-arylcyclopropane-1,2-dicarbonitriles.
