FIELD: chemistry.
SUBSTANCE: invention relates to a method of producing pentacyclo[7.5.0.02.8.05.14.07.11]tetradeca-3,12-diene of formula The method is characterised by catalytic dimerisation of 1,3,5-cycloheptatriene (CHT). The catalyst system used is NbCl5-Et2AlCl. The reaction is carried out with molar ratio CHT:NbCl5:Et2AlCl=10:(0.1-0.3):4, in argon atmosphere, at 20-100°C, in benzene for 8-48 hours.
EFFECT: method enables to separately obtain the end product.
