A convenient and efficient method for the synthesis of 1,4-diaryl-3-butyn-2-ones is described. The carbonylative coupling reactions of (chloromethyl)arenes with terminal arylalkynes proceeded smoothly in the presence of a PdCl2(PPh3)2 catalyst under mild reaction conditions to produce the corresponding 1,4-diaryl-3-butyn-2-ones in satisfactory to excellent yields.

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
