METHOD OF PRODUCING 3-ALKYLIDENE-4-MAGNESABICYCLO[7.3.0]DODEC-5-ENES Russian patent published in 2009 - IPC C07F3/02 

FIELD: chemistry.

SUBSTANCE: proposed invention relates to organomagnesium synthesis, specifically to a method of producing 3-alkylidene-4-magnesabicyclo[7.3.0^1.5]dodec-5-enes (1), which can be used as components of catalyst systems in oligomerisation and polymerisation of olefins and diene hydrocarbons, in fine, industrial organic and organometallic synthesis, as well as in synthesis of biologically active preparations. A method is described for producing new 3-alkylidene-4-magnesabicyclo[7.3.0^1.5]dodec-5-enes (1), which involves reacting an equimolar mixture of cyclonone-1,2-diene and 1,2-alkadiene with EtMgCl in the presence of chemically active magnesium or titanocene dichloride catalyst in an argon atmosphere at room temperature in diethyl ether for 6 to 8 hours.

EFFECT: proposed method allows for obtaining new organomagnesium compounds with high selectivity and high output 63-84%.
