反応手順
The process of Example 18 was repeated except that the catalyst was impregnated with tetramethyltin before use and the feed was 27 g of isobutene and 9.6 g of 1,2-dicyclohex-4-enylethene. The catalyst so prepared contained 6.4% by weight SnMe4. After 30 minutes reaction the products were analysed. 13.7% of the 1,2-dicyclohex-4-enylethylene was converted affording dismutation products with the following seectivities 54% 4-isobutenylcyclohexene and 4.6% 4-vinylcylohexene.
