METHOD OF PRODUCING DIAMANTANE (PENTACYCLO[7.3.1.1.0.0]TETRADECANE) Russian patent published in 2022 - IPC C07C5/31 C07C13/615

Abstract RU 2771230 C2

FIELD: chemical or physical processes.

SUBSTANCE: invention relates to a method of producing diamantane (pentacyclo[7.3.1.1^4,12.0^2,7.0^6,11]tetradecane) by catalytic hydroisomerization of endo-endo-heptacyclo[8.4.0.0^2,12.0^3,8.0^4,6.0^5,9_.0^11,13]tetradecane (binor-S). Method is characterized by that concentrated sulfuric acid is used as catalyst, reaction is carried out at molar ratio [binor-S]:[H₂SO₄]:[solvent]=[1]:[10]÷20]:[10], at 20÷40°C for 7÷15 hours.

EFFECT: readily available catalyst is used; the method is carried out in a single step under mild reaction conditions; the output of diamantane reaches 65%.
