Abstract :

The melt-phase synthesis of dioctyltin (IV) and triphenyltin (IV) benzoates were carried outusing stoichiometric amounts of benzoic acids and the corresponding organotin (IV) compounds.The reagents were ground together in a mortar and fed into a boiling glass tube. A cannula tubewas inserted into the boiling tube to discharge accumulated gaseous products. A syringe ensureda continuous flow of dry Nitrogen gas in the reaction vessel. The compounds are known usingwet Chemistry. Their syntheses via the melt-phase were in good yields. The physical propertiescorresponded to those of the similar compounds prepared by wet chemistry. The IR, 1H and 13CNMR data indicate that coordination to the tin atom is via carboxylate group.
