Abstract

In spite of large steric repulsion between aromatic quinone moiety and dicyanomethylene moiety the title compounds (BDCNBA) were synthesized by TiCl 4-catalyzed reactions of the corresponding aromatic quinones and malononitrile. BDCNBA showed electronic spectra indicating the intramolecular charge-transfer interaction and redox properties similar to 11, 11, 12, 12-tetracyano-9, 10-anthraquinodimethane (TCNAQ) derivatives. BDCNBA ...
