Abstract

sym-Tetracyanoethane reacts with azomethines to give 1,5-disubstituted 2-amino-3,4,4-tricyano-4,5-dihydropyrroles, which upon heating readily split out HCN to give 1,5-diaryl(hetaryl)-2-amino-3,4-dicyanopyrroles. The structures of the dihydropyrroles and pyrroles were confirmed by the PMR, 13C NMR, and mass spectra.
