What is Base hydrolysis of dihalobis(acetylacetonato)technetium(IV) complexes about?

Reaction mechanism of the dihalobis(acetylacetonato)technetium(IV) complexes [TcXz(acac)s, X = Cl and Br] was investigated by means of solvent extraction and spectrophotometric methods. TcXs-(acac), is resistant to the attack of acid. In an alkaline solution, however, it liberates first halide ions and then acetylacetonate ions. As a final product, pertechnetate was recognized. The rate equation is expressed as R = kl [OIF-] [TcX2(acac)2] in a higher concentration of hydroxide ion, whereas it becomes complicated with a decrease in the concentration of hydroxide ion. The respective decomposition rate constants were determined.
