《Cooperativity within the catalyst: alkoxyamide as a catalyst for bromocyclization and bromination of (hetero)aromatics》 was published in Chemical Communications (Cambridge, United Kingdom) in 2020. These research results belong to Mondal, Haripriyo; Sk, Raja Md; Maji, Modhu Sudan. Computed Properties of C14H8Br2 The article mentions the following:
N-Methoxy-1-butanesulfonamide was a recyclable catalyst for the activation of N-bromosuccinimide to perform bromocyclization and bromination reactions of unsaturated carboxylic acids, alkenes and indoles with pendant nucleophiles, and arenes in heptane, where adequate suppression of the background reactions was observed, to yield bromolactones, bromomethyl-substituted heterocycles, fused indolines such as pyrroloindolines, and aryl bromides. The key feature of the active site is the alkoxy group attached to the sulfonamide moiety, which facilitates the acceptance as well as the delivery of bromonium species from the bromine source to the substrates. In the experiment, the researchers used 9,10-Dibromoanthracene(cas: 523-27-3Computed Properties of C14H8Br2)
9,10-Dibromoanthracene(cas: 523-27-3) can be sublimated and oxidized to generate anthraquinone. Soluble in hot benzene and hot toluene, slightly soluble in alcohol, ether and cold benzene, insoluble in water.Computed Properties of C14H8Br2
