experimental part, p. 843 - 860 (2011/01/11)
Various amino, diamino, aminothio, or benzotriazolo compounds derived from the exceedingly versatile 2-nitroperchlorobutadiene (1) gave structurally interesting and physiologically promising nitro-enamines,-imines,-amidines, and hydrazines as well as ring closure reaction products, e. g. pyrimidines and pyrazoles. Most of these reactions turned out to be highly selective with good to very good yields. The structure of the pyrazole precursor (E,E)-1-(benzotriazol-1-yl)-4,4-dichloro-3-(4-ethoxyphenylamino) -1-(4-ethoxyphenylimino)-2-nitrobut-2-ene (30), due to its exceptional substitution pattern, was evidenced by single-crystal X-ray diffraction analysis.
Chemistry of polyhalogenated nitrobutadienes, 2: Synthesis of N-tetrachloroallylidene-N′-arylhydrazines by a formal synproportionation reaction

, p. 2927 - 2933 (2008/02/05)
The reaction of 2-nitropentachlorobuta-1,3-diene with a variety of anilines substituted with electron-withdrawing groups generates, contrary to expectations, N-tetrachloroallylidene-N′-arylhydrazines instead of 1,1-bisaminated substitution products. The imidoyl-type chlorides are capable of undergoing nucleophilic substitution with amines or hydrides. The resulting compounds should exhibit physiological activity, especially for use in crop science. Georg Thieme Verlag Stuttgart.
