Charge-transfer complexes between C-phenyl-N-alkyl nitrones and tetracyanoethylene, 2,3-dichloro-5,6-dicyanobenzoquinone, 7,7,8,8-tetracyanoquinodimethane, tetrafluorocyclohexa-2,5-diene-1,4-dione and tetrachlorocyclohexa-2,5-diene-1,4-dione were studied spectrophotometrically in methylene chloride at 25 deg C.The spectroscopic data indicate that the complexes are weak in nature and the Ph-CH=N -> O group is responsible for the complexation with ?-acceptors.Job's method shows that the stoichiometric ratio of the complexes is 1:1.The effect of temperature and solvents on the stability of the charge-transfer complexes is discussed.
