    • Abstract

       

      Cetyltrimethylammonium hypochlorite (CTAHC) is prepared and used as an oxidizing agent for nitroso group to nitro group. The gem-chloronitroso and vic-chloronitroso compounds are prepared respectively from ketoximes and olefins by reacting with NOCl generated in situ from chlorotrimethylsilane (TMSCl) and iso-amyl nitrite. CTAHC oxidizes gem-chloronitroso and vic-chloronitroso compounds to the corresponding chloronitro derivatives. While gem-chloronitro compounds are obtained in good yields, the vic-chloronitro derivatives are formed in moderate yields, because of the propensity of the vic-chloronitroso group to tautomerize to 𝛼-chlorooxime. The present method is simple and practical, particularly for the preparation of vic-chloronitro compounds, considering the fact that the known methods of their preparation are few and quite involved.
