METHOD OF PRODUCING POLYCYCLOPROPANE HYDROCARBONS Russian patent published in 2018 - IPC C07C13/72 C07C2/86

Abstract RU 2645681 C1

FIELD: chemistry.

SUBSTANCE: invention relates to a method of producing polycyclopropane hydrocarbons of the general formula , R=R'=Me; R=R'=(CH₂)₄, (CH₂)₅; R=Me, R'=cyclo-Pr; R=Me, R'=Ph. The invention is characterized by the fact that 6.6-di-substituted fulvenes of the general formula , where R=R'=Me; R=R'=(CH₂)₄, (CH₂)₅; R=Me, R'=cyclo-Pr; R=Me, R'=Ph, are subjected to interaction with diiodomethane (CH₂I₂) and triethylaluminium (Et₃Al) with a molar ratio of 1,1-di-substituted fulvenes : CH₂I₂ : Et₃Al=1:(2-5):(2-5), in the environment of hexane, in an argon atmosphere at 20°C and atmospheric pressure for 6 h. The yield of polycyclic hydrocarbons (1) is 58-98%.

EFFECT: increasing the yield.
