Abstract

Chlorination of cyclic and linear ketone oximes with aqueous H2O2/HCl in a two-phase dichloromethane-water system selectively affords gem-chloronitroso compounds in yields of up to 94%. One-pot oxidation of the resulting gem-chloronitroso compounds with peracetic acid, prepared in situ, gives gem-chloro­nitroalkanes and cycloalkanes in yields of up to 82%. The advantages of the method are that it is facile and environmentally benign and does not require gaseous chlorine.
