diphenylstannanediol resulted in the methylalumoxane compound L(Me)Al(μ-O)Al(Me)L (3). Compound (LAlO)2B(2, 6-OCH3C6H4)(μ-O) (4) containing the Al2BO3 six-membered ring was accomplished by reacting the precursor LAlH2 (2) with 2, 6-dimethoxyphenylboronic acid. The two compounds were characterized by 1H NMR spectroscopy, elemental analysis, and single-crystal X-ray structural analysis.

The synthesis of 3 compounds of a series of dibutyl(IV) di-4-chlorobenzoate, diphenyl(IV) di-4-chlorobenzoate and triphenyltin(IV) 4-chlorobenzoate have successfully been performed by reacting the dibutyltin(IV) dichloride, diphenyltin(IV) dichloride and triphenyltin(IV) chloride respectively via the dibutyltin(IV) oxide, diphenyltin(IV) dihydroxide and triphenyltin(IV) hydroxide with 4-chlorobenzoic acid. All compounds synthesized were well characterized by 1H and 13C NMR, IR and UV-Vis spectroscopies as well as based on the microanalytical data. The anticorrosion activity of these compounds were tested on Hot Roller Plate (HRP) mild steel in DMSO-HCl solution using potentiodynamic method. The results revealed that the triphenyltin(IV) 4-chlorobenzoate clearly showed the strongest inhibitor activity compared to the other derivatives, while diphenyltin(IV) compounds were better than that of dibutyltin(IV) analogous. The results reported here indicated that the optimal activity were depended on the ligand attached to the metal centre and might also be related to the number of carbon atoms present in the organotin(IV) used.
