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 20-22C and atmospheric pressure for 8-12 hours. ^ EFFECT: method enables to obtain desired products with high regioselectivity. ^ 14 ex, 1 tbl |
