PURPOSE:To obtain an alkenylcyclohexene in high yield, by cyclodimerization of a chain conjugated diolefine with a carbon number 4-6. CONSTITUTION:In the above process a cuprous compound containing an alkylsulfoxy ion, a perfluoroalkylsulfoxy ion, an arylsulfoxy ion, a tetrafluoroboric ion, a tetraphenylboric ion or a hexafluorosphoric ion is used as a catalyst. |
