ABSTRACT OF THE DISCLOSURE Chemical Process A process for the preparation of an ester of dicarboxylic acid from an alkene, carbon monoxide is provided. The process is catalysed by a catalyst which comprises a platinum group metal, for example palladium, and a copper compound. To avoid catalyst deactivation the process is carried out in the presence of a dihydrocarbyl peroxide which is reduced to a hydrocarbyl alcohol under the process conditions. The process can be used, for example, to prepare succinate esters from ethylene, carbon monoxide an alcohol and a dihydrocarbyl peroxide such as di-tertiary butyl peroxide.
