Synthesis and Characterization of Metal Complexes Derived from Dimedone Derivatives

Reactive methylene group at C2 position in the 1, 3 dicarbonyl compounds plays an important role in the synthesis of a variety of organic ligands. Condensed compounds 3, 5, 7 were synthesized by reaction with dimedone and different aromatic aldehydes. Synthesized condensed compounds 3, 5 and 7 were on reaction with hydroxyl amine hydrochloride to yield oximes ligands 8, 9 and 10 respectively. The synthesized oxime derivatives 8, 9, 10 were used further to synthesize metal complexes of cobalt 11, 12 and 13 respectively. All ligands were characterized by Mass, IR, 1HNMR and CMR spectroscopic technique. The cobalt complexes obtained were characterized by using IR. , TG-DTA, Magnetic susceptibility, and LC-MS techniques.
