p-Nitrobenzyl alcohol is found to undergo a hydroxide ion catalyzed photoredox reaction (eq 1), while m-nitrobenzyl alcohol undergoes a water and hydronium ion catalyzed process (eq 3).

The photochemistry of several m- and p-nitrobenzyl alcohols (1-5) has been studied in aqueous solution.These compounds react via an intramolecular photoredox pathway to give reduced and oxidized moieties of the substituent groups.The reaction is an example of a new type of photoreaction of nitro-substituted aromatic derivates that is not observed in organic solvents, the presence of water being essential.This effect is exemplified by measuring the quantum efficiency as a function of molpercent water in aqoeous acetonitrile, methanol, and formaldehyde: the reaction efficiency decreases rapidly as water is depleted in the mixture.Catalytic efficts due to the hydronium and hydroxide ions were studied: the para derivatives exhibited hydroxide ion catalysis; the meta derivatives exhibited hydroniumn ion catalysis.Quantum yields, solvent isotop effects, and α-deuterium isotope effects are reported for the parent derivatives.

When irradiated with u.v. light in deoxygenated aqueous solutions, m-nitrobenzyl alcohol (1) is found to give m-nitrobenzaldehyde (2), and the azoxycompounds (3) and (4).
