The photodegradation of aqueous alcoholic solutions of fenarimol at λ ≥ 250 nm has been examined. UV irradiation of an aqueous methanolic solution for 24 h yielded two photoproducts, identified as 2,4′‐dichlorobenzil and p ‐chlorobenzoic acid, while irradiation of a solution in aqueous isopropanol yielded p ‐chlorobenzoic acid and two additional products identified as 2,4′‐dichlorobenzophenone and o ‐chlorobenzoic acid. A mechanism for the formation of the photoproducts is suggested. © 2000 Society of Chemical Industry
