Abstract

The kinetics of oxidation of ketones by thallium (III) has been studied in acid perchlorate medium. The reaction does not indicate enolization to be the rate controlling step in the reaction mechanism. The kinetic rate law (1) has been observed. -d[TlIII] / dt= k1Kh [Tl(III)Ketone] / ([H+] + Kh) Where Kh is the hydrolysis constant of the oxidant. A plausible reaction mechanism is suggested conforming to the rate law (1). Activation parameters were evaluated.
