One-pot aromatic bromination-rearrangement catalyzed by GaCl3 was written by Arisawa, Mieko;Suwa, Atsushi;Ashikawa, Masanori;Yamaguchi, Masahiko. And the article was included in ARKIVOC (Gainesville, FL, United States) in 2003.Formula: C8H8Br2 This article mentions the following:
Reaction of monoalkylbenzenes with bromine in the presence of a catalytic amount of GaCl3 (5 mol %) initially gives o/p-bromination products, which are converted into mixtures containing considerable amounts of the m-brominated products. Notably, the bromination of dimethyl-, trimethyl-, and tetramethylbenzenes gives dibromo- and/or tribromoarenes, which are converted into monobromoarenes. In the experiment, the researchers used many compounds, for example, 2,5-Dibromo-1,3-dimethylbenzene (cas: 100189-84-2Formula: C8H8Br2).
2,5-Dibromo-1,3-dimethylbenzene (cas: 100189-84-2) belongs to organobromine compounds. Organo bromine compounds are versatile compounds and are widely used in diverse fields. Organo bromine derivatives are used in the dye sector, as an indicator in analytical chemistry (Bromothymol blue is a popular indicator). In the pharmaceutical industry organo bromine derivatives are used as sedatives, vasodilators, antiseptic agents, and anticancer agents.Formula: C8H8Br2
