| titleOfInvention | Preparation of unsaturated diesters by catalytic oxidative carbonylation of diolefins |
| abstract | A process for the preparation of an unsaturated diester having the formula <IMAGE> wherein R is alkyl having 1 to 8 carbon atoms or aralkyl having 6 carbon atoms in the ring and from 1 to 4 carbon atoms in the alkyl moiety, and R1, R2, R3 and R4 are the same or different and are each hydrogen, halogen, alkyl having 1 to 4 carbon atoms or aryl having 6 carbon atoms in the ring, by reacting carbon monoxide and oxygen with a diolefin having the formula <IMAGE> wherein R1, R2, R3 and R4 are as aforesaid, in the presence of a catalytic amount of a platinum group metal compound, a copper or iron oxidant salt compound, a soluble vanadium salt and a stoichiometric amount of a dehydrating agent. Optionally, an anhydrous-halogen containing acid may be included. Alternatively, a ligand or coordination complex compound of the metal salt compound, and catalytic quantities of an alcohol may be employed. |
