“…Oxidation of TEOA can be achieved in presence of several oxidants such as periodate, hypochlorous acid, chlorine dioxide , and hexacyanoferrate (III). But in those cases further oxidation of formaldehyde was not reported or the oxidation of the formaldehyde was extremely slow and, therefore, formaldehyde was reported as the end product (Shukla et al, 1973).

“…In neutral medium, potassium hexacyanoferrate (III) has been utilized for the oxidation of aliphatic amines [96]. In basic medium, potassium hexacyanoferrate (III) has been widely used for the oxidation of various types of organic compounds like aldehydes [97][98][99][100][101], amines [102][103][104][105][106][107][108], alcohols and diols [109][110][111][112][113][114][115], sulphur compounds [116][117][118][119][120][121][122], acids [123][124][125][126][127], sugars [128,129], hydrazines, amino acids [130] [131], acyloins, As(III) [132,133], hypophosphite [134], hydrocarbons [135] and phenols [136,137]. The electronically favourable CNligand reduces the barrier for an electronic flow from highest occupied molecular orbital of substrate to the lowest unoccupied molecular orbital of metal complex.…”

The review surveys the development of kinetics and various oxidising agents which can be used during the study of chemical kinetics along with oxidation of some organic substrates by hexacyanoferrate (III) /HCF (III). Since HCF (III) is acting as relatively poor oxidant, it acts as a selective outer-sphere reagent applicable for most of the easily oxidisable substrates and normally it is used as free radical interceptor; because of which it converts into a species acting as an efficient one electron oxidant mainly for the octahedral complexes in comparative study.

“…The rate constant decreases with increase in Ce(IV) concentration (Table -1). This decrease in oxidation rate is due to the formation of an unreactive dimeric [Ce(IV)]2 species [12][13][14] which increases with [Ce(IV)] 2Ce(IV) [Ce(IV)]2 The oxidation rates of the alcohols understudy followed the sequence:…”

The controlled oxidation of the aliphatic alcohols 2-propanol, 2-butanol and 3-methyl-1-butanol to the corresponding carbonyl compounds has been carried out using Ce (IV) in acidic medium in the absence and presence of transition metal ions of the first series. The aliphatic alcohols are widely used as diluents in the perfumery industry. The oxidation reaction was monitored under pseudo unimolecular conditions with respect to [Ce (IV)] in the temperature range 303-318 K. Aliquots of the reaction were withdrawn at regular time intervals, quenched using ice and the unreacted oxidant was estimated titrimetrically using standard ferrous ammonium sulphate with ferroin as indicator. The pseudo first order rate constants were determined from the linear plots of log (a-x) versus time. It was observed that the rate increases with alcohol concentration but decreases with Ce(IV) concentration. This has been attributed to the formation of unreactive dimeric [Ce(IV)]2 at higher concentration of Ce(IV). Potassium sulfate was used to study the effect of ionic strength on the oxidation rate. The thermodynamic activation parameters were determined from the effect of temperature on the oxidation rate. The Ru(VIII), Os(VIII) and Cr(VI) ions have been exhaustively used to catalyse a variety of organic reactions. In the present study, relatively low-cost metal ions of the first transition series have been used as effective catalysts for the oxidation of the fragrance alcohols under study. The reaction mechanism suggested for the oxidation process involves intermediates with hypervalent ions i.e., M(III). The catalytic efficiency of the metal ions is based on the stability of the complexes formed as reaction intermediates which in turn depends on the charge density of the metal ions involved. We have observed some discrepancies as the experimentally determined sequence of catalytic efficiency of metal ions does not follow the theoretically expected sequence. Suitable reaction mechanisms have been suggested for the oxidation of the alcohols in the absence and presence of transition metal ions. In the absence of metal ions, the oxidation rates of aliphatic alcohols the sequence: 2-propanol > 2-butanol > 3-methyl-1-butanol. The relative rates of oxidation of alcohols have been discussed and explained on the basis of structures, steric factors and isomeric characteristics of the perfumery alcohols under study.
