    Abstract: The invention relates to a method for producing triazolyl methyl oxiranes of formula I wherein A and B are the same or different and independently represent C1-C4-alkyl, phenyl-C1-C2-alkyl, C3-C6-cycloalkyl, C3-C6-cycloalkenyl, tetrahydropyranyl, tetrahydrofuranyl, dioxanyl or phenyl, the phenyl radical being able to carry between one and three substituents selected from the group containing halogen, nitro, C1-C4-alkyl, C1-C4-alkoxy, phenoxy, amino, C1-C2-halogenalkyl or phenylsulfonyl. Said compounds are produced by converting an oxirane of formula II wherein A and B have the aforementioned designation, and L represents a leaving group which can be substituted in a nucleophilic manner, with a) 1,2,4-triazole (IIIa) and a molar equivalent of an inorganic base, or b) a 1,2,4-triazolide of formula IIIb wherein Me represents an alkali metal atom or a quaternary ammonium ion, in a dipolar aprotic solvent having an OH-acid compound content of less than 0.5 % and/or having an NH-acid compound content of less than 2.5 %.
