METHOD OF PRODUCING exo-TRICYCLO[4,2,1,0]NONANE-3-SPIRO-1'-(3'-SELENIUM)CYCLOPENTANE Russian patent published in 2011 - IPC C07F11/00 

FIELD: chemistry.

SUBSTANCE: invention relates to a method of producing exo-tricyclo[4,2,1,0^2.5]nonane-3-spiro-1'-(3'-selenium)cyclopentane, which can be used in fine organic synthesis, as well as in synthesis of biologically active heterocyclic compounds. The method involves reaction of 3-methylene-exo-tricyclo[4,2,1,0^2.5]nonane with triethylaluminium in the presence of a zirconocene dichloride catalyst (Cp₂ZrCl₂) in an argon atmosphere at room temperature and atmospheric pressure in hexane for 4 hours and then addition of selenium (Se) to the reaction mass, where selenium is taken in amount which is equimolar to ALEt₃ and stirring at temperature 80°C for 5-7 hours. Output of the end product after hydrolysis of the reaction mass is between 70% and 84%.

EFFECT: high yield.
