Problems related to directed synthesis of complex functionalized heterocyclic compounds constitute an important field of modern organic chemistry. Target structures may be constructed in several steps via successive introduction of particular substituents. However, this approach is often associated with low conversion of initial reactants, high expenditures of time, energy, and labor, the necessity

Based on the reaction of available adducts of tetracyanoethylene (TCNE) and aromaticketones (4-aryl-4-oxoalkane-1,1,2,2-tetracarbonitriles) with hydrogen chloride, several aryl substituted 2-halogencinchomeronic dinitriles were synthesized. We found that aryl substituted derivatives, in contrast to alkyl substituted ones, possess an intensive solid state fluorescence. The relationship between the
