<p>Disclosed are processes for preparing phenylacetaldehydes of the structure (I) (see fig. I) where the substituents X are 2,4-dichloro, difluoro, tri-fluoro, tetrafluoro, p-trifluoromethyl, 2-methyl-4-fluoro, haloalkoxy or haloalkylthio radicals or are adjacent CL, F, CF3, alkyl, alkoxy, haloalkoxy and/or haloalkylthio radicals. Some of these compounds which are useful as intermediates for the preparation of insecticides, are new.</p> |
