Abstract: The invention relates to a process for preparing 2-halopyridinecarboxamides of primary aromatic monoamines I which have a substituent other than hydrogen in the ortho-position to the amino group by reaction of 2-halopyridinecarbonyl chloride II with the aromatic monoamine I, which comprises carrying out the reaction in a solvent mixture comprising water and at least one water-immiscible organic solvent in the presence of none or less than 10 mol %, based on the 2-halopyridinecarbonyl chloride II, of a base other than I or II.

Abstract: The present invention relates to a process for preparing trioxime derivatives of the formula I in which the substituents R 1 and R 2 are identical or different and each is cyano, alkyl, haloalkyl or cycloalkyl, and R 3 and R 4 are identical or different and each is alkyl, haloalkyl, cycloalkyl, alkylcarbonyl or arylalkyl, by the following reaction steps in water without isolation of the intermediates: A) nitrosation of 1,3-diketones of the formula II to give monooximes of the formula III, B) oximation of III with hydroxylamine derivatives of the formula IV H 2 N-OR 3' IV in which R 3' is hydrogen or a group R 3 to give bisoximes of the formula V, C) alkylation of V with alkylating agents or acylation of V with acylating agents to give compounds of the formula VI and D) subsequent oximation of VI with hydroxylamine to give compounds of the formula I.
