KAISERLICHESIMPERIAL
Durch Einwirkung von Chlor- oder Bromessigsäure auf Brenzkatechin oder Pyrogallol werden Halogenacetophenone dargestellt nach folgender Gleichung:By the action of chloro- or bromoacetic acid on catechol or pyrogallol Halogenacetophenones are represented according to the following equation:
C. Ä (O H), + ClCHtCO OH
■;-. = ClCH2COC6H2(O H)5 +H2O.
Die Halogenderivate reagiren leicht mit Basen unter Bildung von Amidoacetophenonen, z.B.:C. Ä (OH), + ClCHtCO OH
■; -. = ClCH 2 COC 6 H 2 (OH) 5 + H 2 O.
The halogen derivatives react easily with bases to form amidoacetophenones, e.g.
Cl CH2C OCn K, (O H)3 + Cn H, NH2 = CaH. NHCH2COC6H2(OH)3 + HCl. Cl CH 2 C OC n K, (OH) 3 + C n H, NH 2 = C a H. NHCH 2 COC 6 H 2 (OH) 3 + HCl.
Beispiel i. Zur Herstellung von Chlor-· acetopyrogallol werden 50 Theile Pyrogallol, 40 Theile Chloressigsäure und 40 Theile Phosphproxychlorid erwärmt, bis die Schmelze ' stürmisch Chlorwasserstoff entwickelt. Man giebt hierauf das doppelte Volumen heifsen Wassers hinzu und filtrirt. Das Filtrat erstarrt zu einem Krystallbrei von langen farblosen Nadeln, welche aus Wasser umkrystallisirt werden. , ; Example i. To prepare chloroacetopyrogallol, 50 parts of pyrogallol, 40 parts of chloroacetic acid, and 40 parts of phosphproxychloride are heated until the melt violently evolves hydrogen chloride. Double the volume of hot water is then added and the mixture is filtered. The filtrate solidifies to a crystalline pulp of long, colorless needles, which are recrystallized from water. , ;

Bei· dieser Reaction kann man das Pyrogallol durch Brenzkatechin ersetzen, die Chloressigsäure durch Bromessigsäure, beide Halogenfettsäuren durch ihre Salze, Ester, Chloride, Anhydride oder Amide, das Phosphoroxychlorid durch die anderen üblichen Condensationsmittel, z. B. Zink- oder Zinnchlorid oder Schwefelsäure. Die Reaction gestaltet sich dann ganz so, wie sie von Nencki und dessen Schülern' (Journal für prakt. Chemie, Bd. 23, S, 147 und 538) beschrieben und später im Patent Nr. 49149 benutzt worden ist.In this reaction the pyrogallol can be replaced by pyrocatechol, the chloroacetic acid by bromoacetic acid, both halogen fatty acids by their salts, esters, chlorides, Anhydrides or amides, the phosphorus oxychloride by the other common condensation agents, z.
