FIELD: chemistry. ^ SUBSTANCE: invention relates to an improved method of producing azoxystrobin by reacting a compound of formula (II): with 2-cyanophenol or a salt thereof in the presence of 2.5-40 mol. % 1,4-diazabicyclo[2,2,2]octane and an acid acceptor, where W is a methyl(E)-2-(3-methoxy)acrylate group C(CO2CH3)=CHOCH3. 1,4-diazabicyclo[2,2,2]octane is mixed with a compound of formula (II) only in the presence of 2-cyanophenol or when conditions are such that the compound of formula (II) and 1,4-diazabicyclo[2,2,2]octane are not capable of reacting with each other. ^ EFFECT: method enables to obtain a product with high output using a certain order of adding components. ^ 12 c, 18 ex |
