An improved process for oxacylating olefins in the gaseous phase which comprises using a supported catalyst comprising palladium and a carrier having a total pore volume of from 0.4 to 1.2 ml/g, less than 10% of the total pore volume being attributable to micropores having a diameter of less than 30 A. Catalysts of this type are much more efficient than conventional catalysts.
