METHOD FOR PRODUCING EXO-PENTACYCLO5.4.0.0.0.0UNDECANE-4-SPIRO-1'(3'-ETHYL-3'-ALUMINE)CYCLOPENTANE

摘要

A process for preparing exo-pentacyclo [5.4.0.02,9.03,6.08,10] undecane-4-spiro-1 '- (3'-ethyl-3'-aluminum) cyclopentane general formula (1)! ! characterized in that 4-methylene-exo-pentatsiklo [5.4.0.02,9.03,6.08,10] yndekan reacted with triethylaluminum (Et3Al) in the presence of a catalyst tsirkonatsendihlorida (Cp2ZrCl2) in a molar ratio of 4-methylene-exo-pentatsiklo [5.4. 0.02,9.03,6.08,10] yndekan: Et3Al: Cp2ZrC2 = 10: (10-14) :( 0.6-1.0) in an argon atmosphere at normal pressure in hexane for 5-7 hours.
