The methods for synthesis of promising norbornene monomers from norbornadiene and quadricyclane are summarized. A strategy for their synthesis is discussed, combining theoretical and experimental approaches to the selection of catalysts and the conditions for carrying out stereoselective reactions. The mechanisms of catalytic reactions of synthesis of norbornene monomers, as well as the progress in the macromolecular design of functional polymeric materials based on them, are considered. The data on industrial processes of production of polynorbornenes and areas of their use are presented. The bibliography includes 297 references.

The activity and selectivity of palladium, copper, platinum, and nickel catalysts in the decarbon ylation of stearic acid into hydrocarbons were studied at a 14 atm hydrogen pressure and temperatures of 300-350°C. If γ alumina was used as a carrier, the catalysts formed the series Pd > Cu > Pt > Ni according to desired product yields. Quantum chemical simulation was performed to show that the free energy of acti vation increased in the same series. The same metals deposited on mixed tungsten and zirconium oxides cat alyzed decarbonylation with a low yield of C 17 hydrocarbons, likely because such a superacidic carrier could catalyse cracking of olefins or their oligomers formed.
