| titleOfInvention | Preparation of azoxystrobin |
| abstract | Disclosed is a process for preparing a compound of formula (I) such as azoxystrobin, which comprises either (a) reacting a compound of formula (II) with 2-cyanophenol, or a salt thereof, in the presence of between 0.1 and 40 mol % of 1,4-diazabicyclo[2.2.2]octane (DABCO), or (b) reacting a compound of the formula (III), with a compound of the formula (IV) or a salt thereof, in the presence of between 0.1 and 40 mol % of 1,4-diazabicyclo[2.2.2]octane; wherein W is the methyl (E)-2-(3-methoxy)acrylate group C(CO2CH3)=CHOCH3 or the methyl 2-(3,3-dimethoxy)propanoate group C(CO2CH3)CH(OCH3)2, or a mixture of the two groups, and wherein 1,4-diazabicyclo[2.2.2]octane is not mixed with the compound of formula (II) or the compound of formula (III) unless (i) 2-cyanophenol or the compound of formula (IV) is present; or (ii) 1,4-diazabicyclo[2.2.2]octane is present as an acid salt or (iii) conditions are such that 1,4-diazabicyclo[2.2.2]octane and the compound of formula (II) or the compound of formula (III) are not able to react with each other; with the proviso that when between 0.1 and 2 mol% 1,4-diazabicyclo[2.2.2]octane is used, the 1,4-diazabicyclo[2.2.2]octane is not added last. |
