- PROCESS FOR NITROALKANE RECOVERY BY AQUEOUS PHASE RECYCLE TO NITRATION REACTOR
-
Disclosed are a process and an apparatus for synthesizing nitroalkanes by reaction of a hydrocarbon feedstock with aqueous nitric acid. Energy and capital costs may be reduced by recycling a majority of the aqueous phase back to the reactor.

- Radical-Nucleophilic Substitution (SRN1) Reactions. Part 6. N-Anions of Diazoles in SRN1 and Oxidative Additions
-
The anions of imidazole, benzimidazole, 5(6)-nitrobenzimidazole, and 5(and 6)-nitro-1H- and -2H-indazoles have been shown to undergo oxidative addition to the anion of 2-nitropropane (using potassium ferricyanide and sodium persulphate), and SRN1 reactions with Me2C(X)NO2 (X = Cl, Br, and NO2) to yield the corresponding 1-(1-methyl-1-nitroethyl) derivatives.The anions of 5(6)-nitrobenzimidazole and 5(6)-nitro-1H- and -2H-indazoles underwent reaction with p-nitrobenzyl chloride by a SRN1 and/or SN2 mechanism to yield the corresponding 1-(p-nitrobenzyl) derivatives.The ambident anions of 5- and 6-nitrobenzimidazole, 5-nitro-1H- and -2H-indazoles, and 6-nitro-1H- and -2H-indazoles gave ca. 50:50 mixtures of the N-1 alkylation products resulting from respective pairs of ambident anions.The 1-(1-methyl-1-nitroethyl) derivatives of benzimidazole and 5- and 6-nitro-1H-indazole underwent further substitution of the aliphatic nitro group with the respective diazole to yield 2,2-di(benzimidazol-1-yl)-, 2,2-dipropanes.

- THE CHEMISTRY OF DIACYL PEROXIDES - VIII. THE REACTIONS BETWEEN POLYFLUORODIACYL PEROXIDES AND 2-NITRO-2-NITROSOPROPANE--GENERATION OF BIS(POLYFLUOROALKYL) NITROXIDES
-
Thermal decomposition of 2-nitro-2-nitrosopropane (4) in F113 (CCl2F-CClF2) solution involves C-NO bond fission and forms acetone as the major product.In the presence of polyfluorodiacyl peroxide (3), the oxidation of 4 by 3 to 2,2-dinitropropane (5) is the predominant reaction and bis(polyfluoroalkyl) nitroxide (1) is generated as one of the by-products.

- SRN1 AND OXIDATIVE ADDITION REACTIONS OF NITROIMIDAZOLE ANIONS
-
The anions of 2- and 4(5)-nitroimidazoles react with aliphatic substituted nitro compounds and p-nitrobenzyl chloride by a SRN1 mechanism, or by oxidative addition to the anion of 2-nitropropane, to yield 1-alkyl-2-(or 4-)-nitroimidazoles.
