PROCESS FOR THE PREPARATION OF NITRO COMPOUNDS AND METHOD FOR THE REMOVAL OF NITROGEN DIOXIDE

, (2008/06/13)
In the invented process for producing a nitro compound, an organic substrate and nitrogen dioxide are reacted in the presence of oxygen or are reacted in a molar ratio of nitrogen dioxide to the organic substrate of less than 1 to yield a corresponding nitro compound. The reaction may be performed in the presence of N-hydroxyphthalimide or other imide compounds. Such organic substrates include (a) aliphatic hydrocarbons, (b) alicyclic hydrocarbons, (c) non-aromatic heterocyclic compounds each having a carbon atom on a ring, which carbon atom is bonded to a hydrogen atom, (d) compounds each having a carbon-hydrogen bond at the adjacent position to an aromatic ring, and (e) compounds each having a carbon-hydrogen bond at the adjacent position to a carbonyl group. This process can efficiently nitrate an organic substrate even under relatively mild conditions.

The study of S(RN)1 reaction between 2-chloromethyl-3-nitroimidazo[1,2-a] pyridine and 2-nitropropane salts has been extended to various aliphatic, cyclic and heterocyclic nitronate anions. From C-alkylation products, base-promoted nitrous acid elimination afforded new potential pharmacological derivatives with a trisubstituted double bond at the 2 position.
