METHOD FOR COMBINED PRODUCTION OF PENTACYCLO[7.5.0.0.0.0]TETRADECA-3,12-DIENE AND PENTACYCLO[8.4.0.0.0.0]TETRADECA-8,12-DIENE Russian patent published in 2015 - IPC C07C2/42 C07C2/52 C07C13/64 B01J31/38 B01J31/22 B01J31/02

Abstract RU 2551282 C1

FIELD: chemistry.

SUBSTANCE: invention relates to a method for combined production of pentacyclo[7.5.0.0^2.8.0^5.14.0^7.11]tetradeca-3,12-diene of formula

and pentacyclo[8.4.0.0^3.7.0^4.14.0^6.11]tetradeca-8,12-diene of formula

The method includes homogenisation of 1,3,5-cycloheptatriene (CHT) in the presence of a Ti-containing catalyst system, and is characterised by that the catalyst used is Ti(acac)₂Cl₂-Et₂AlCl, the reaction is carried out with molar ratio CHT:Ti(acac)₂Cl₂:Et₂AlCl=10:(0.1-0.3):4, in an argon atmosphere, at 5-80°C, in benzene for 6-72 hours.

EFFECT: method enables to use a more stable catalyst and reduces power consumption.
