ABSTRACT OF THE DISCLOSURE Esters or carboxylic acids are prepared from olefins containing at least two carbon atoms by reacting the olefin with carbon monoxide in the presence of: (i) a first complex of a selected Lewis acid with the ester or carboxylic acid, whichever is the reaction product recovered; (ii) a second complex of the Lewis acid with an alcohol, if an ester is being prepared, or with water, if a carboxylic acid is being prepared; and (iii) a metal carbonyl compound containing a Group IB transition metal in the first oxidation state; and by recovering the reaction product(s). The preferred olefin is propylene, the pre- ferred ester to be prepared is methylisobutyrate, the preferred metal is copper and the preferred Lewis acid is boron trifluoride.
