Abstract

When 2-aryl-5,6-tetramethylene-3,3,4-tricyano-2,3,4,5-tetrahydropyridine-4-carboxamides are subjected to the action of acids, they are isomerized, forming either 2-aryl-5,6-tetramethylene-3,3,4-tricyano-1,2,3,4-tetrahydropyridine-4-carboxamides or 3-aryl-1,8-tetramethylene-6-oxo-2,7-diazobicyclo[3.2.1]octane-4,4,5-tricarbonitriles.
