METHOD OF PRODUCING 1-ALKYL-1-ALKOXY-2-ARYLCYLOPROPANES Russian patent published in 2011 - IPC C07C43/188 C07C41/01 

FIELD: chemistry.

SUBSTANCE: present invention relates to a method of producing 1-alkyl-1-alkoxy-2-arylcyclopropanes of general formula (1): where Ar = Ph, o-MeC₆H₄, p-MeC₆H₄; R=CH₃, C₂H₅, C₄H₉; R'=CH₃, C₂H₅, which can be used in fine organic synthesis, particularly synthesis of biologically active compounds, having pyrethroid, acaricidal, pesticidal, growth-regulating, fungicidal and antibacterial activity. The method involves reacting arylethylene of general formula Ar-CH=CH₂, where Ar=Ph, o-MeC₆H₄, p-MeC₆H₄, with an equimolar amount of an ester of general formula RCO₂R', where R=CH₃, C₂H₅, C₄H₉; R'=Me, Et, in the presence of diethylaluminium chloride (Et₂AlCl), magnesium (Mg, powder) and a Cp₂ZrCl₂ catalyst in molar ratio Ar-CH=CH₂: RCO₂R': Et₂AlCl : Mg : Cp₂ZrCl₂ = 10 : 10 : (20-30) : (10-14) : (0.8-1.2) in an argon atmosphere at temperature 20-22°C and atmospheric pressure for 8-12 hours.

EFFECT: method enables to obtain desired products with high regioselectivity.
