Abstract: Process for the preparation of thioethers of ketoxime carbamates (I) in which R to R have the meaning given in the claims and description, by reacting an appropriate compound (II) in which R , for example, denotes an optionally substituted alkyl radical, with an appropriate compound (III) in the presence of a strong base to give the corresponding ketosulphoxide (IV) reacting this to give the corresponding mercaptoketone (V) and reacting this with hydroxylamine to give the corresponding oxime and reacting the oxime either with an appropriate isocyanate R -NCO, or with phosgene and an appropriate alkylamine R R NH or with an appropriate alkylcarbamoyl chloride R R NCOCl.
