Abstract
The present invention relates to a process for preparing alkylpyridine N-oxides of formula (I) from the corresponding unsubstituted 3-alkylpyridines or the 5-alkylpyridines correspondingly substituted in the 2 position of formula (II) in the presence of at least oxidizing agent, water, organic solvent and catalyst.
Claims15
A process for preparing compounds of formula (I),
- in which R1 is linear or branched C1-C10 alkyl, which may be unsubstituted, monosubstituted or polysubstituted,
- or in which R1 is C3-C8 cycloalkyl, which may be unsubstituted, monosubstituted or polysubstituted,
- or in which R1 is aralkyl, which may be unsubstituted, monosubstituted or polysubstituted, and in which R2 is hydrogen, chlorine, bromine, fluorine or cyano,
- comprising at least the reaction of compounds of formula (II),
- in which R1 and R2 have the definition given for formula (I),
- in the presence of at least oxidizing agent, water, organic solvent and catalyst.
