METHOD OF PRODUCING 2-ENDO-ETHYL-5-EXO-ETHYLPENTACYCLO[8.4.0.0.0.0]TETRADECA-8,12-DIENE Russian patent published in 2015 - IPC C07C2/42 C07C2/52 B01J31/38 B01J31/22 B01J31/02 C07C13/64

Abstract RU 2551284 C1

FIELD: chemistry.

SUBSTANCE: invention relates to a method of producing 2-endo-ethyl-5-exo-ethylpentacyclo[8.4.0.0^3.7.0^4.14.0^6.11]tetradeca-8,12-diene of formula (1) The method is characterised by that homogenisation of 7-ethyl-1,3,5-cycloheptatriene (C₉H₁₂) is carried out in the presence of a catalyst system TiX₂Cl₂-Et₂AlCl (X=Cl, acac, i-PrO), with molar ratio C₉H₁₂:TiX₂Cl₂:Et₂AlCl = 10:(0.1-0.3):4, in an argo atmosphere at 20-100°C in benzene for 8-48 hours.

EFFECT: method enables to separately obtain the desired compound.
