FIELD: chemistry.

SUBSTANCE: invention relates to a method of producing norbornene oligomers (bicyclo[2.2.1]hept-2-ene) with a terminal double bond of general formula H(C₇H₁₀)_n(C(R)=CH(R')), where n=6, 11, 10, 26; R=R'=H; R=H and R'=CH₃ or R=CH₃ and R'=H; C₇H₁₀ - norbornene repeating fragment, by reacting a nickel complex, norbornene and boron trifluoride etherate in the atmosphere of gaseous α-alkene. The method is characterised by that the complex used is bis(acetylacetonato)nickel combined with triphenylphosphine, triethylaluminium, followed by addition of methanol as a proton-donor compound, with the molar ratio Ni(acac)₂:norbornene:PPh₃:AlEt₃:MeOH:BF₃OEt₂=1:2000:2:3:10:100, and the process is carried out at room temperature in toluene as an organic solvent.

EFFECT: use of the disclosed method increases efficiency of the process.
