Irradiation of 1-(1-naphthyl)buta-1,3-diynes (1)–(3) in aqueous sulphuric acid yields both type-A (4), (6), (8) and type-B (5), (7), (9) hydration products. The type A/B product ratio was 0.8–1 : 1 in neutral conditions, while the ratio increases as the acidity of the medium increases. The fluorescence of compounds (1) and (3) decreased but that of compound (2) was invariant with increasing acidity
