Kinetics and Mechanism of Electron Transfer Reactions: Oxidation of Crotyl Alcohol by Peroxomonosulfate in Aqueous Acidic Medium

Abstract

The kinetics and mechanism of oxidation of crotyl alcohol by peroxomonosulfate has been studied, and the species of the peroxomonosulfate are discussed to find out the role of activated species. A plausible reaction mechanism is suggested, and a derived rate law corresponds to all experimental observations. The activation parameters such as energy and entropy of activation have been calculated as 37.21 ± 0.5 kJ mol−1 and −148.91 ± 2.7 J K−1 mol−1, respectively, by employing the Eyring plot.

Spectrophotometric Kinetic and Mechanistic Investigation of Chlorpromazine Radical Cation with Hexachloroiridate (IV) in Catalyzed Aqueous Acid Medium

“…[37][38][39][40][41] In our laboratory, kinetic investigations have been carried out with various reactants in acidic medium. [42][43][44][45][46] The present work summarizes the results of series of experiments to explore the electron transfer path from chlorpromazine hydrochloride to hexachloroiridate (IV) in acidic medium spectrophotometrically. The results suggest formation of free radical cation as intermediate which subsequently undergoes the electron transfer and ultimately leads to sulfoxide derivative.…”

Oxidation of crotyl alcohol byN-chloro-4-methylbenzene sulphonamide in acidic medium and in alkaline media in the presence of os(VIII) catalyst-a kinetic pathway

“…In most, kinetic studies of oxidation of unsaturated alcohols have been studied in the absence [17] and presence of heterogeneous catalysts [18,19]. Transition metal ions such as Ru(III) [20], Ag(I) [21], Os(VIII) [22], Pd(III) [23] were also taken as homogenous catalysts.…”

A kinetic and mechanistic study of the osmium(VIII)-catalysed oxidation of crotyl alcohol by hexacyanoferrate(III) in aqueous Alkaline medium

“…Most of the kinetic studies on the oxidation of unsaturated alcohols have been made in the absence 34 and presence of heterogeneous catalysts. 35,36 Also transition metal ions such as Ru(III), 37 Os(VIII), Pd(III) 38 and Ru(II) have been employed as homogeneous catalysts.…”
