Zusammenfassung:Process for the preparation of cis-2-(1H-1,2,4-triazol-1-ylmethyl)-2-(halophenyl)-3-(halophenyl)oxira ne I by epoxidation of Z-3-(1H-1,2,4-triazol-1-yl)-2-(halophenyl)-1-(halophenyl)propene II, in which halogen is in each case fluorine, chlorine or bromine, by reaction of the crude epoxidation product with one or more reducing agents, in which the reducing agent is added to the reaction mixture in a substantially higher amount than is necessary for destroying any peroxide compounds present.
