A vapor phase process for the preparation of unsaturated aldehydes, carboxylic acids and mixtures thereof which comprises contacting a gaseous mixture of an open-chain olefin of from 3 to 8 carbon atoms, water and oxygen at an elevated temperature up to about 250.degree. C. with a solid catalyst consisting essentially of a catalytically effective amount of noble metal selected from the group consisting of palladium, gold, silver, copper and mixtures thereof promoted by a solid acid consisting of a mixture of molybdenum trioxide and titanium dioxide wherein the atomic ratio of Mo/(Ti+Mo) is between about 0.4 and 0.8.
