Abstract

The synthesis of novel substituted 11, 11, 12, 12-tetracyano-1, 4-anthraquinodimethanes (1, 4-TCAQs) 3 from the corresponding 1, 4-anthraquinones 2 by reaction with the Lehnert's reagent is described, thus confirming the validity of this procedure to obtain different substitution patterns on the benzene fused quinone ring. W-vis spectra of the novel compounds show the presence of an intramolecular charge-transfer band in the blue part ...
