ABSTRACT Olefins such as propylene can be oxidized directly to .alpha.,.beta.-unsaturated carboxylic acids such as acrylic acid with air or oxygen in an aqueous medium under moderate reaction conditions employing a novel palladium metal catalyst which has been activated by contacting it with propylene at temperatures of from about 60 to 150°C for about 10 to 120 minutes. Similarly, isobutylene may be oxidized to methacrylic acid, and butene-1 can be converted to crotonic acid. The advantage of the invention includes maintaining high yields under moderate reaction conditions which is made possible by use of the novel catalyst which has improved catalytic activity resulting from its activation in the substantial absence of oxygen.
