An inexpensive and highly selective method for cerium(IV) sulfate-catalyzed hydration of alkynes was provided. Treatment of alkynes (1 mmol) with Ce(SO4)2 (0.1 mmol), H2SO4 (conc. 0.06 mL), water (0.02 mL) and benzene (5 mL) at 70 ℃ afforded the corresponding ketones in moderate to excellent yields.

Key words: hydration reaction, cerium(IV) sulfate, ketone, alkyne
