Abstract  

Base hydrolysis of Tc(acac)3 and Ru(acac)3 was studied in 0.1–1M NaOH at different temperatures. In spite of apparent similarity of these complexes Tc(acac)3 showed more complexity than Ru(acac)3 in kinetic behavior. Tc(acac)3 decomposes with a rate, d[Tc(acac)3]/dt=(k1[OH–]+ +k2[OH–]2)[Tc(acac)3], where k1 and k2 at 25°C are (1.67±0.11)×10–5 mol–1·s–1 and (1.71±±0.14)×10–5 mol–2·s–1, respectively. Decomposition of Ru(acac)3 is expressed by the rate equation d[Ru(acac)3]/dt=k[OH–][Ru(acac)3], where k at 37°C is (8.01±0.23)×10–6 mol–1·s–1.
