Abstract
An N-substituted imidochloride or mixture thereof is prepared by reacting a ketoxime or a hydrohalide thereof with phosgene in the absence of water, at a temperature which from or after the commencement of the reaction exceeds 20 DEG C., in such a way that at all or substantially all times while the reaction temperature is above 20 DEG C., not more than two mols. of phosgene are available per mol. of ketoxime. Preferably a polar solvent is used, e.g. nitromethane, nitrocyclohexane, chlorobenzene, chloroform, acetonitrile or benzonitrile. In examples: (1) benzophenone oxime gives N-phenylbenzimidochloride; (2) acetophenone oxime gives N-phenylacetimidochloride; (3) diethylketoxime gives N-ethylpropionimidochloride hydrochloride; (4) cyclohexenone oxime gives 2-chloroazacyloheptene-1,2 hydrochloride, which with aniline yields 2-phenylaminoazacyclo-1,2-heptene; (5) cycloheptanone oxime gives 2-chloroazacyclo-1,2-octene hydrochloride which with aniline yields the anilido compound.
