METHOD OF PRODUCING DIAMANTANE (PENTACYCLO[7,3,1,1,0,0]TETRADECANE) Russian patent published in 2018 - IPC C07C5/13 C07C5/31 C07C13/615

Abstract RU 2645914 C1

FIELD: chemistry.

SUBSTANCE: invention relates to the method of producing diamantane (pentacyclo [7.3.1.1^4.12.0^2.7.0^6.11] tetradecane) of the formula

(1),

Endo-endo-hexacyclo [9.2.1.0^2.10.0^3.8.0^4.6.0^5.9]) tetradecane (endo-endo-GCTD) is isomerized in the presence of ionic liquid 2AlCl₃-Et₃N⋅HCl, at the molar ratio [endo-endo-GTZD]:[IL]=[1]:[0.5÷9], under the conditions of 50°C, 8 h. Under optimal conditions, with a full conversion (12), the yield of diamantane (1) reaches 92%.

EFFECT: increasing the yield.
