TRIFLUORO(OXALATO)MANGANATE(III) OXIDATIONS OF THIOSEMICARBAZIDE, SEMICARBAZIDE AND THEIR DERIVATIVES

Potassium trifluoro(oxalato)manganate(m) (E-0' = +1.07 V) is quite sta ble in the solid state but undergoes decomposition in aqueous solution . The solution stability of the complex in different acid media is stu died. The oxidation reactions of potassium triflouro(oxalata)manganate (m) with substrates like thiosemicarbazide,thiosemicarbazones, semicar bazide, semicarbazones and metal complexes of thiosemicarbazide have b een investigated. The reactions have been followed titrimetrically and also potentiometrically in some cases. The stoichiometries of the rea ctions are established and the oxidation products identified.
