Abstract The photodegradation of 1,3‐dimethyl‐1‐(2‐(3‐fluorobenzylthio)‐1,3,4‐thiadiazol‐5‐yl)urea as a thin film and in solution is described. The two photoproducts from thin‐film photolysis were characterized by spectral and synthetic methods. The X‐ray crystal structure of one of the photoproducts is also reported. The rearrangements were shown to involve an S ‐to‐ N benzyl migration, followed by a sulfur‐oxygen substitution.
