2.4- Dinitro-N-propyl

Bei der Reaktion von Diisopropylamin mit l-Chlor-2,4-dinitro-benzol in Benzol bei 60° entsteht das erwartete N,N-Diisopropyl-2,4-dinitro-anilin nur in sehr geringer Ausbeute als Hauptprodukt entsteht das nur eine Isopropyl-Gruppe enthaltende 2,4-Dinitro-N-iso-propyl-anilin neben einer geringeren Menge an 2,4-Dinitro-N propyl-anilin1. Ahnliche Er-gebnisse erhalt man mit dem entsprechenden Aryl-fluorid und -bromid sowie bei Durch-fiihrung der Reaktion in Methanol oder Dimethyl-sulfoxid.

The possibility of ring closure was expected to depend on molecular geometry. Thus, photolysis of n-propyl azide (7) in cyclohexane produced only the imine (8) in 59% yield, isolated as the 2,4-dinitro-phenylhydrazone (9). Irradiation of phenylethyl azide (10) resulted...

A kinetic smdy of the formation of zwitterionic adducts (28) from 1,3,5-trinitrobenzene and diazabicyclo derivatives indicates that reactions are surprisingly slow, with rate constants many orders of magnitude lower than those for related reactions with primary or secondary amines. The use of rapid-scan spectrophotometry was necessary to study the kinetics of reaction of 4-substimted-2,6-dinitro-A -n-butylanilines (29) with n-butylamine in DMSO the two processes observed were identified as rapid deprotonation to give the conjugate base and competitive a-adduct formation at the 3-position. The reactions of MAf-di-n-propyl-2,6-dinitro-4-trifluoromethylaniline (30), the herbicide trifluralin, and its A -ethyl-A -n-butyl analogue with deuteroxide ions and with sulfite ions in [ H6]DMS0-D20 have been investigated by H NMR spectroscopy. With deuteroxide a-adduct formation at the 3-position is followed by...

Nitroimidazoles are readily made by nitration of imidazole or 1-substituted imidazoles in concentrated sulfuric acid (see Section 7.2.1). It is much more difficult to make 2-nitroimidazoles since direct nitration is seldom observed in the 2-position. Although electrophilic nitrodehalogenation reactions, too, occur mainly at C-4(5) [1], Katritzky has recently selectively nitrodeiodinated 2,4,5-triiodoimidazole to prepare 2,4(5)-dinitro-5(4)-iodo-and 2,4,5-triiiitroimidazoles, albeit in poor yield [2], Other routes to 2-nitroimidazoles include those which react a diazonium fluoroborate with the nitrite ion, and methods which oxidize 2-amino derivatives, themselves often only available by laborious sequences. The most appealing routes to 2-nitroimidazoles are the methods which make the 2-lithio derivative and treat it with a source of nitronium ion (e.g. n-propyl nitrate or N2O4) [3-5] (see Section 7.2.2).
