METHOD FOR PRODUCING EXO-TRICYCLO4.2.1.0NONANE-3-SPIRO-1'-(3'-SELENIUM)CYCLOPENTANE

摘要

A process for preparing exo-tricyclo [4.2.1.02,5] nonane-3-spiro-1 '- (3'-selenium) cyclopentane general formula (1)! ! characterized in that 3-methyl-exo-tricyclo [4.2.1.02,5] nonane is reacted with triethylaluminum (AlEt3) in the presence of a catalyst tsirkonatsendihlorida (Cp2ZrCl2) in a molar ratio of 3-methyl-exo-tricyclo [4.2.1.02,5] nonane: AlEt3: Cp2ZrCl2 = 10: (10-14) :( 0.4-0.6) in an argon atmosphere at room temperature and atmospheric pressure in hexane for 4 hours, followed by the addition thereto of selenium (Se), taken in equimolar of relative to the amount of AlEt3, and stirring at a temperature of 80 ° C for 5-7 hours.
