Process for the preparation of diesters of hexene-1,6-dioic acid. …The subject is more specifically a process for the preparation of diesters of 3-hexene-1,6-dioic acid by reaction of carbon monoxide and of an alcohol with at least one butene disubstituted with acyloxy groups in the presence of a catalyst based on palladium and on a halide, characterised in that the reaction is conducted in a basic aprotic polar solvent in the presence of at least one inorganic halide whose cation is chosen from the cations of alkali metals and the cations of alkaline-earth metals and whose anion is chosen from chloride and bromide.
