Abstract

The oxidation activity of di and tri-organotin complexes derived from the condensation reaction of organotin salts of chloride with para-methoxy cinnamic acid was successfully synthesized, identified, and analyzed. The synthesized complexes (1-4) were shown to be more effective than the ligand from which they were made. In addition, when compared to the other complexes, complex 2 (diphenyl tin carboxylate) is the most effective at oxidation. Several techniques were used to diagnose the produced compounds, including FTIR, 1H-NMR, and Sn119-NMR, while two approaches, DPPH and CUBRAC, were used to investigate the oxidation activity. The reactions of para-methoxy cinnamic acid and several of substituted tin chlorides gave the corresponding tin complexes with good yields. The antioxidant activity of the prepared complexes was found to be higher than that of the ligand derived from. [ABSTRACT FROM AUTHOR]

Abstract

4-Aminoantipyrine was used as ligand to prepare new complexes of triphenyltin, di-butyl and dimethyl-tin complexes by condensation reaction with the corresponding organotin chloride salts. The complexes were identified by different techniques, such as infrared spectra, (tin and proton) magnetic resonance and elemental analyses. The antioxidant activity of 4-aminoantipyrine and prepared complexes were studied by two different methods; Free radical scavenging activity DPPH and CUPRRAC methods. Tri and di-tin complexes gave high percentage inhibition than ligand with both methods due to tin moiety, also triphenyltin carboxylate complex was the best compared with the others.
