METHOD OF PRODUCING TRICYCLO[4,2,1,0]-NONANE-3-SPIRO-1'-BUTANE Russian patent published in 2009 - IPC C07C2/86 C07C1/26 C07C13/547 C07C13/72 

FIELD: chemistry.

SUBSTANCE: invention relates to a method of producing tricyclo[4.2.1.0^2'5]nonane-3-spiro-1'-butane of general formula (1), , characterised by that, 3-methylenetricyclo[4.2.1.0^2,5]nonane is reacted with triethylaluminium Et₃Al in the presence of zirconocene dichloride catalyst Cp2ZrCl2 in molar ratio 3-methylenetricyclo[4.2.1.0^2,5]nonane:Et₃Al: Cp₂ZrCl₂=10:(10-14):(0.4-0.6) in an argon atmosphere at temperature 20°C and normal pressure in hexane, for a period of 5 to 7 hours with subsequent addition at -10°C of diethyl ether in a volume equal to that of hexane taken, triphenylphosphine Ph₃P and palladium acetylacetonate Pd(acac)₂ in amount equimolar to Cp2ZrCl2. Freshly distilled allyl chloride is then added in threefold excess of taken Et₃Al, and temperature is brought to room temperature and stirring is continued for 5 more hours.

EFFECT: said compound can be used in fine organic synthesis, in production of liquid-crystalline systems, and biologically active substances.
