Hydration of a wide range of alkynes to the corresponding ketones has been afforded in high yields at room temperature by using gold(I)−phosphine complexes as catalyst, with no acidic cocatalysts required. Suitable substrates covering alkyl and aryl terminal alkynes, enynes, internal alkynes, and propargylic alcohols, including enantiopure forms, are cleanly transformed to the corresponding ketones
