Weygand und Grisebach (214) fanden einen Austausch zwischen dem Brom in p-Bromanilin und Bromwasser beim Fallen des p-Brom-anilins als Tribromanilin. Auch Brombenzol tauscht sein Halogen mit Bromwasser aus. [Pg.162]

Anilin, 4-Methyl-, 4-Chlor- und 4-Brom-anilin werden mit Diphenylselenoxid in Gegenwart von Triethylamin zu den entsprechenden Azobenzolen (Azobenzol, 4,4 -Dimethyl-, 4,4 -Dichlor-, 4,4 -Dibrom-azobenzol) oxidiert7. [Pg.68]

Die Umsetzung von aktivierten Ethenen (z. B. Butenon, Acrylsaure-ester, Acrylnitril) mit N-Methyl-anilin oder 2-Brom-anilin und 1,4-Benzoehinon in Tetrahydrofuran in Gegen-wart von Lithiumchlorid und 0,1 Mol-Aquivalenten Bis-[acetonitril]-palladium-dichlorid fiihrt zur Aminierung der Methylen-Gruppe der Ethen-Derivate2. [Pg.793]

The direct chlorination or bromination of aniline takes place more easily than that of benzene, the result being the symmetrical tri-chlor or tri-brom aniline, viz., i-amino 2-4-6-tri-chlor benzene, C6H2CI3-(NH2) and I-amino 2-4-6-tri-brom benzene, CeH2Br3(NH2). The mono-halogen anilines are prepared by reducing mono-chlor nitro benzenes, or by halogenating acetanilide and then hydrolyzing. [Pg.558]

Leb has found that p- and o-chlor-aniline are obtained by the electrolytic reduction of nitro-benzene suspended in fuming hydrochloric acid, nitro-benzene dissolved in alcoholic hydrochloric acid, and nitrobenzene dissolved in mixtures of hydrochloric and acetic acid. With hydrobromic acid the corresponding brom-anilines are formed. [Pg.86]
