实验步骤: 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.

实验步骤: In a control run, the following reaction mixture was prepared in a Fisher-Porter aerosol compatibility bottle: 0.25 grams (1.5 mmol) of ferric chloride, 0.3 grams (2.5 mg-atom) of tin powder and 0.3 grams (4.5 mmol) of sodium nitrite. The bottle reactor was evacuated then flushed with nitrogen followed by the addition of 10 ml of THF. The mixture was cooled with dry ice and 18.3 grams (339 mmol) of 1,3-butadiene added. This reaction mixture was heated to 75° C. with stirring. During this time, the original dark green solution changed in color to an orange-brown color. After 5 hours, the reaction was terminated and the reaction mixture allowed to cool to room temperature and stand for 1 day. Pressure on the reactor was still at 25 psig indicating there had been little, if any, conversion of 1,3-butadiene to the dimer. The results of this run indicate that one does not obtain dimerization of 1,3-butadiene to 4-vinylcyclohexene if one attempts to form the iron nitrosyl halide simultaneously with the dimerization.

实验步骤: Dicyclopentadiene and 4-vinylcyclohexene in equimolar mixture were heated in an autoclave at 240° C. for 4-4.5 hours. The reaction product was diluted with cyclohexane and passed through a packed bed of alumina to remove the t-butyl-catechol inhibitor introduced with the reactants. The resulting product mixture was distilled in a wiped film evaporator at 3 mm Hg pressure at 90° C. to produce a light fraction containing unreacted vinylcyclohexene and dicyclopentadiene and the mono-adducts of 4-vinylcyclohexene and cyclo-pentadiene. A 150g sample of this distillate was vacuum distilled using a 10-tray Oldershaw column to give four fractions. The fourth fraction, 65g, was shown by gas chromatographic analysis to consist of 0.15% dicyclopentadiene, 88.3% endo-5-(3-cyclohexen-1-yl)-2-norbornene, 6.1% exo-5-(3-cyclohexen-1-yl)-2-norbornene and two additional components present in the amount of 1.9% and 2.4% which are believed to be isomeric adducts of the formula ##STR9## several additional components totalling about 0.4%, 0.4% tricyclopentadiene and about 0.4% unidentified components. Analysis of the fraction by nuclear magnetic resonance indicated about 87 mole percent of the endo adduct, about 9 mole percent of the exo adduct and about 5% of the isomeric adducts. to remove the t-butyl-catechol inhibitor introduced with the reactants The resulting product mixture was distilled in a wiped film evaporator at 3 mm Hg pressure at 90° C. to produce a light fraction distilled to give four fractions
