Claims10
A process for the preparation of diesters of alkanedioc acids, which process comprises reacting at a temperature in the range of from 20.degree. C. to 200.degree. C. and a pressure in the range of 5 to 200 bar a dihydrocarbyl peroxide with carbon monoxide and with an alpha-alkene having 2 to 10 carbon atoms per molecule in the presence of a solvent and a catalyst system formed by combining (a) a noble metal or a compound thereof of Group VIII of the Periodic Table of the Elements and (b) a cupric salt.
