The photochemical behaviour of 3‐styryl‐5‐phenyl‐(5‐methyl)‐1,2,4‐oxadiazoles in methanol at 254 nm has been investigated. A photoinduced rearrangement to the quinoline system has been pointed out and explained as proceeding through an initial photolysis of the ring ON bond, followed by a six membered ring closure reaction involving the styryl moiety.
