Abstract
A process for preparing diesters of carboxylic acids by oxidative carbonylation of C.sub.2 -C.sub.20 olefins, C.sub.1 -C.sub.20 monohydric aliphatic alcohols and carbon monoxide in an atmosphere containing molecular oxygen at a temperature of from room temperature to about 350.degree. C. in the presence of a carrier-supported catalyst containing a platinum group metal, wherein said catalyst comprises, supported on a carrier, a post-reduced compound of a platinum group metal and a post-reduced compound of a metal having an atomic number of not less than 22 selected from the group consisting of metals of Groups Ib, IIb, III, IV, V, VI and VIIb of the periodic table.
