Kinetics and mechanisms of redox reactions in aqueous solution. Part 4. Oxidation of diols by aquamanganese(III) ions in aqueous perchloric acid

Mahendra Mehta,  Ratan Raj Nagori  and  Raj Narain Mehrotra 

Abstract

The kinetics of oxidations of butane-1,4-, pentane-1,5-, and hexane-1,6-diols and of 3-methoxybutan-1-ol by aquamanganese(III) ions have been investigated in aqueous perchloric acid at constant ionic strength (4 mol dm–3). The reaction has a first-order dependence both on [MnIII] and [Substrate], but is independent of [MnII]. The rate decreases with increasing [H+] at constant ionic strength, becoming less sensitive at >3 mol dm–3 HClO4. The present rate data do not help to distinguish between inner- and outer-sphere mechanisms, although complex formation is indicated by spectrometry. A probable mechanism is suggested and the activation parameters are reported.
