Charge Transfer Molecular Complexes of Arylidene Anthranilic Acid Derivatives with  -Electron Acceptors.

Research Abstract
X-Benzylidenesanthranilic acid molecular complexes with π-acceptors, tetracyanoethylene, 2,3-dichloro-5,6-dicyano-p-benzoquinone and chloranil, have been studied. The intramolecular hydrogen bonding that exists in such compounds greatly inhibits the transition of the nitrogen azomethine n-electrons. The formation constant values and molar extinction coefficients of the p-dimethyl-aminobenzylideneanthranilic acid-DDQ CT complexes have been determined in CH2Cl2, C2H4Cl2 and CHCl3 in the temperature range 10-30oC. Such CT complexes are of strong n-π type

Synergistic extraction of cobalt(II) complexes with toluene-3,4-dithiol in presence of some benzylamines

Research Abstract
The synergistic extraction of cobalt(II) complexes with toluene-3,4-dithiol (TDT) in presence of monobenzylamine (BA), dibenzylamine (DBA) and tribenzylamine (TBA) has been investigated. The stoichiometry of the adducts formed was established from the extraction data. Values of the formation constant,B ex, in presence of the amine ligands have been determined. It is found that the extraction ability decreases in the orderDBA TBA>BA.
