FIELD : chemistry.SUBSTANCE : invention relates to a method of producing bicyclo[4, 2, 1]nona-2, 4-dienes of general formulawhere R=H, -(CH)-; R=Me, Bu, Hex, Ph, Bn, -(CH)-, -(CH)-, CHTMS, R=H, -(CH)-, Ph, CHTMS via catalytic reaction of 1, 2-dienes with 1, 3, 5-cycloheptatriene (CHT). The catalyst system used is Ti(acac)Cl-EtAlCl, the 1, 2-diene used is a compound of general formula(where R, R, Rare described above), the reaction is carried out with molar ratio 1, 2-diene : CHT : Ti(acac)Cl : EtAlCl=(10-14) : 10 : (0.1-0.3) : 4 in an ampoule at 20-80°C, in benzene for 6-48 hours.EFFECT : invention reduces power consumption and enables to use a more stable catalyst.17 ex, 1 tbl |
