Abstract: A process for preparing halomethylbenzoyl cyanides I Ph-CO-CNI (Ph=phenyl radical substituted by chloromethyl or bromomethyl which, if desired, can additionally carry 1-4 further radicals) by reacting halomethylbenzoyl chlorides II Ph-CO-ClII with an alkali metal cyanide or transition metal cyanide, if appropriate in an organic diluent, and novel halomethylbenzoyl cyanides I' I' (X=halogen, C1-C4-alkyl, C1-C4-alkoxy, CF3, C1-C5-alkyl-(C1-C5-alkyl)hydroxyimino or C1-C5-alkyl-(C2-C5-alkenyl)hydroxyimino; m=0 to 4 and Y=chloromethyl or bromomethyl) are described. The halomethylbenzoyl cyanides I are important intermediates for the synthesis of plant protection agents.

Abstract: 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.
