摘要
The preparation of Z-1,2-diarylallyl chlorides of the general formula I ##STR1## in which R.sup.1 and R.sup.2, independently of one another, are hydrogen, halogen, alkyl, haloalkyl, alkoxy, haloalkoxy or a substituted aromatic radical, and n and m are 1, 2 or 3, by dehydrating chlorohydrins of the formula II ##STR2## in which the radicals are as defined above, at up to 50° C. in an inert ether or carboxylic acid ester as solvent and in the presence of a carboxylic anhydride and an organic or inorganic acid, the conversion thereof into azolylmethyloxiranes, and novel intermediates are described.
