Allylic acetoxylation of cyclohexene (96) at 80 °C affords 3-acetoxycyclohexene (97) in 67% yield (Scheme 36). It was found that the catalytic double-bond isomerization of 3-phenylpropene proceeds by the action of an electrochemically generated 17-electron Co(II) species [132]. The cobalt(III)-mediated electrooxidative decomposition of chlorinated organics, that is, l,3-dichloro-2-propanol, 2-monochloro-propanol, and so on, has been performed... 

A method for preparing a Ti/Cr203 electrode has been developed for the indirect electrooxidation of 2-propanol to acetone [149]. Epoxidation of alkenes has been performed using oxo[5,10,15,20-tetrakis(2,6-dimethyl-3-sulfonatophenyl)... 

Komori and Nonaka [499] reported the first example of an electrochemical enantiomer-differentiating reaction When racemic 2,2-dimethyl-1-phenyl-1-propanol was oxidized at a poly(L-valine)-coated anode, 43% optically pure (S)-(—)-2,2-dimethy 1-1-phenyl-1-propanol was recovered as an unreacted part. Yamagishi and Aramata [500] also found electrooxidative optical resolution of a racemic Co(l,10-phenathroline)3 complex by a chiral clay-coated anode, and Yoshinaga and coworkers [501] electrore-ductively resolved racemic Co(acetylacetonato)3 by using optically active supporting electrolytes. 

Simultaneously with the investigations on Pt, the reactivity of the primary C3 alcohols on gold elecrodes in acid media (0.5 mol dm H2SO4) was studied by the same authors. The results obtained, in agreement with previous observations, confirm once more that no reactions with n-propanol occur at a gold electrode in acid medium. Bulk allyl alcohol oxidation leads to the formation of CO2 and acrolein, while propargyl alcohol electrooxidation produces CO2 and propargyl aldehyde. Some of the main conclusions are as follows ... 

Of the primary alcohols, a number of studies have investigated the electro-oxidation characteristics of ethanol, 2-propanol, and butanol. There have been several reviews on the electro-oxidation of these molecules on Pt, Au, and Pt/Au alloys. A number of trends have been observed for the electrooxidation of primary alcohols, including (i) the rate of electro-oxidation is dependent upon the pH of the solution, with R being the electrocatalyst in acidic media, (ii) the reactivity of the alcohols is governed by the position of the functional group on the backbone (primary alcohols are more reactive than secondary compounds, and tertiary alcohols show little reactivity), (iii) for the primary and secondary alcohols the first step in the dissociative adsorption...

There are few reports on the electrooxidation of 1-propanol and 2-propanol on Pd-based catalysts in alkaline electrolytes. This suggests that more research work on these alcohols is needed because 2-propanol is less toxic than methanol and its electrochemical oxidation is of great interest due to its particular molecular structure. Pd Pti xix = 0-1) nanocatalysts on Ti foil were prepared by Lu et al. [40] using electrochemical methods, and they determined its activity towards the electrooxidation of 2-propanol. Pdo.8Pto.2/Ti showed better catalytic activity and stability for the electrooxidation of 2-propanol in alkaline mediiun based on the bifunctional mechanism. Pd-Au/C catalyst was synthesized by chemical reductimi method using NaBELt as the reducing agent. Pd-Au (4 1)/C showed...
