sym-TATRACYANOETHANE IN THE SYNTHESIS OF HETEROCYCLES. 4. SYNTHESIS OF 1-ALKYLIDENEIMINO-2-AMINO-3,4,4-TRICYANO-4,5-DIHYDROPYRROLES BY THE REACTION OF sym-TETRACYANOETHANE WITH AZINES

sym-Tetracyanoethane reacts with aldazines and ketazines to give 1-alkylideneimino-2-amino-3,4,4-tricyano-4,5-dihydropyrroles, some of which are thermally converted to 1-alkylidene-2-amino-3,4-dicyanopyrroles or 5,5-disubstituted 1-alkylideneimino-2-amino

A comparative analysis of the mass spectra of 5-substituted 1-alkylideneimino-2-amino-3,4-dicyanopyrroles and their 2,5-dihydro and 4,5-dihydro derivatives makes it possible to find the typical fragmentation pathways that characterize each group of compounds and to detect the presence of tautomeric amino-imino forms in the gas phase.
