Procedure

13.1 g of the catayst prepared in Example 17 was charged into a steel reactor under a blanket of nitrogen. To this was added 8.4 g of 1,2-dicyclohex-4-enyl ethylene and 27 g of isobutene. The reactor was sealed and rocked. After 1 hour at ambient temperature, the products were analysed. 3.7% of the 1,2-dicyclohex-4-vinyl ethylene was converted affording dismutation products with the following selectivities 31.3% 4-isobutenylcyclohexene and 69.% 4-vinylcyclohexene.
