Sodiumethanethiolate in methanol is an efficient reducing agent for gem-bromonitro compounds; treatment of the resultant nitronates with a protic acid or with N-chlorosucccinimide gives high yields of the corresponding nitro or gem-chloronitro compounds, respectively.

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.
