Halogen derivatives of quinone. Part II was written by Ling, Arthur R.;Baker, Julian L.. And the article was included in Journal of the Chemical Society, Transactions in 1892.COA of Formula: C6H3BrClNO3 This article mentions the following:
The behavior of chlorotribromoquinone and trichlorobromoquinone toward alkalis was investigated. Chlorotribromoquinone, when heated with potassium hydroxide solution, yields chlorobromanilic acid, whereas the action of potassium hydroxide on quinone produces potassium chlorobromanilate. The action of potassium hydroxide and sodium hydroxide on quinone leads to the formation of a compound consisting of chlorobromanilate and bromanilate. Trichlorobromoquinone, when treated with potassium hydroxide, produces a uniform product consisting of chloranilate and chlorobromanilate, contrary to previous experiments in which chlorobromanilic acid was obtained. In the experiment, the researchers used many compounds, for example, 4-Bromo-2-chloro-6-nitrophenol (cas: 58349-01-2COA of Formula: C6H3BrClNO3).
4-Bromo-2-chloro-6-nitrophenol (cas: 58349-01-2) belongs to organobromine compounds. Bromine is more electronegative than carbon (2.9 vs 2.5). Consequently, the carbon in a carbon–bromine bond is electrophilic, i.e. alkyl bromides are alkylating agents. Commercially available organobromine pharmaceuticals include the vasodilator nicergoline, the sedative brotizolam, the anticancer agent pipobroman, and the antiseptic merbromin.
