METHOD FOR COMBINED PRODUCTION OF PENTACYCLO7.5.0.0^2,8.0^5,14.0^7,11TETRADECA-3,12-DIENE AND PENTACYCLO8.4.0.0^3,7.0^4,14.0^6,11TETRADECA-8,12-DIENE

摘要

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.;1 tbl, 7 ex
