WO3ZnO/Fe3O4 is used as a magnetic photocatalyst in the preparation of 2-substituted benzimidazoles in EtOH at RT. The key feature is the in situ photocatalytic oxidation of benzyl alcohols to benzaldehydes under atmospheric air in the absence of further oxidant.

The oxidation of aromatic alcohols to produce carbonyl compounds is of great significance in fine chemical production. The traditional oxidation produces waste gas and pollutes the environment during the reaction. As a new field, photocatalysis has attracted people's attention because of its environmental friendliness. At present, there have been much research on TiO2, or noble metal modified TiO2 to catalyze alcohol oxidation, but the high cost is not conducive to large-scale production. Herein, a Ni@C/TiO2 catalyst was prepared by in-situ hydrothermal synthesis. This catalyst has a better oxidation effect on benzyl alcohol than Ni@C supported on TiO2 on the market and has a good catalytic effect on aromatic alcohols with different substituents. It is more interesting that the selectivity of the product can be adjusted by choosing different reaction solvents. The highly active catalyst with low cost and wide applicability has certain significance for the large-scale use of photocatalytic alcohol oxidation.

The mechanism of the permanganate oxidation of di- and tri-arylcarbinols has been studied in aqueous sulfuric acid. With both kinds of alcohols the rate-controlling step in solutions more acidic than H0 −0.50 was found to be the ionization of the carbinol to give the carbonium ion followed, it is believed, by rapid reaction with permanganate ion to form the ester which decomposes rapidly to products. In the case of the tertiary alcohols the decomposition probably proceeds via a 1,2-aryl shift. The effect of substituents is correlated with σ+ in both cases, ρ+ being −1.02 and −1.39 for the secondary and tertiary series. The acidity function which governs both reactions is H0. Tri(p-tolyl)carbinol is exceptional in that its oxidation in solutions more acidic than HR −2.6 is second-order and is governed by the HR acidity function.
