Abstract

Cycloalkanone oxime hydrochlorides are prepared by treating a cycloalkane with nitrosyl chloride in the presence of hydrogen chloride and under actinic radiation, the reaction being effected at -10 to 50 DEG C. and nitrosyl chloride being fed to the reaction zone at a partial pressure of 5-80 mm. The hydrogen chloride may be fed to the reaction zone in admixture with the nitrosyl chloride or it may be dissolved in the cycloalkane before the nitrosyl chloride is introduced. The nitrosyl chloride may be diluted with an inert gas, e.g. carbon dioxide or nitrogen, and the cycloalkane may be diluted with an inert liquid, e.g. benzene or carbon tetrachloride. The oxime hydrochlorides may be converted into the free oximes in known manner, and the free oximes in turn may be converted into the corresponding lactams. Examples are given of the treatment of cyclohexane and cyclo-octane. The treatment of cycloheptane also is mentioned.
