FIELD: chemistry.
SUBSTANCE: invention relates to the method for producing dimer of norbornadiene-endo-endo-hexacyclo[9.2.1.02.10.03.8.04.6.05.9]tetradecene-12 by dimerization of norbornadiene under the action of the catalytic system Fe (acac)3-AlEt3-CH2(CN)2 at the molar ratio of catalyst and reagent [Fe(acac)3]:[CH2(CN)2]:[AlEt3]:[norbornadiene]=1:1÷6:6÷10:100÷200 in toluene, at 110°C for 0.2 h. With complete conversion of norbornadiene, the yield of endo-endo-hexacyclo[9.2.1.02,10.03.8.04.6.05.9]tetradecene-12 reaches 93%.
EFFECT: increasing the yield.
