Abstract: The present invention relates to a process for the preparation of E-oxime ethers of phenylglyoxylic esters of the general formula I in which X and Y denote halogen, alkyl, alkoxy, CF3, C(=NOR)R (R = alkyl and alkenyl), by reacting oximes of the formula II with a methylating agent in an organic diluent, and process for the preparation of E-oximes of phenylglyoxylic esters of the formula II by isomerising the E/Z oximes.

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.

Abstract: Z-1,2-Diaryl-allyl chlorides of formula (I) and the corresponding epoxides (V) are new: where Ar1 = (R1)n-phenyl; Ar2 = (R2)m-phenyl; R1 and R2 are each H, halo, 1-7C alkyl, 1-6C haloalkyl, 1-5C alkoxy (opt. halo substd.), or aromatic gp. (opt. substd. by 1-3 of R1 and R2; n and m = 1-3.
