METHOD OF PRODUCING BICYCLO[4,2,1]NONA-2,4-DIENES Russian patent published in 2015 - IPC C07C2/52 B01J31/02 B01J31/22 B01J31/38 C07C13/28

Abstract RU 2551278 C1

FIELD: chemistry.

SUBSTANCE: invention relates to a method of producing bicyclo[4,2,1]nona-2,4-dienes of general formula where R=H, -(CH₂)₆-; R¹=Me, Bu, Hex, Ph, Bn, -(CH₂)₆-, -(CH₂)₅-, CH₂TMS, R₂=H, -(CH₂)₅-, Ph, CH₂TMS via catalytic reaction of 1,2-dienes with 1,3,5-cycloheptatriene (CHT). The catalyst system used is Ti(acac)₂Cl₂-Et₂AlCl, the 1,2-diene used is a compound of general formula (where R, R¹, R² are described above), the reaction is carried out with molar ratio 1,2-diene:CHT:Ti(acac)₂Cl₂:Et₂AlCl=(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.
