Abstract

Abstract Intermolecular charge transfer (CT) complexes of aromatic aldehyde thiosemicarbazones with some π-acceptors such as 7,7,8,8-tetracyanoquinodimethane, 2-(dicyanomethylene)indane-1,3-dione and 9-dicyanomethylene-2,4,7-trinitrofluorene have been studied spectrophotometrically. Aromatic aldehyde thiosemicarbazones, and thiosemicarbazide reacted with tetracyanoethylene via CT-complex formation to give 1,3-thiazine and pyridazine derivatives.
