The use of chlorine bleach (5% NaOCl) for the halogenation-oxidation of oximes to gem-chloronitro compounds is reported. Chlorine bleach afforded satisfactory yields when employed alone either at room temperature or under ultrasonic irradiation.
A mild and efficient process for one-stepconversion of oximes into gem-halo-nitro compounds using Oxone® and sodium chloride or potassium bromide is described.
