Direct and Efficient Preparation of<i>gem</i>-Chloronitro Compounds or Nitro Compounds from<i>gem</i>-Bromonitro Compounds

Abstract

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.
