《Copper and L-(-)-quebrachitol catalyzed hydroxylation and amination of aryl halides under air》 was written by Liang, Xinjie; Li, Hui; Du, Fangyu; Zhang, Yongsheng; Dong, Jinhua; Bao, Xuefei; Wu, Ying; Chen, Guoliang. Formula: C7H5BrO2 And the article was included in Tetrahedron Letters in 2020. The article conveys some information:
L-(-)-Quebrachitol, a natural product obtained from waste water of the rubber industry, was utilized as an efficient ligand for the copper-catalyzed hydroxylation and amination of aryl halides to selectively give phenols and aryl amines in water or 95% ethanol. In addition, the hydroxylation of 2-chloro-4-hydroxybenzoic acid was validated on a 100-g scale under air. In the experimental materials used by the author, we found 4-Bromobenzoic acid(cas: 586-76-5Formula: C7H5BrO2)
4-Bromobenzoic acid(cas: 586-76-5) has been used to study the metabolic fate of 2-,3-and 4-bromo benzoic acids in rat hepatocytes incubation using high temperature liquid chromatography.Formula: C7H5BrO2 It was used in bromine-specific detection of the metabolites of 2-,3-and 4-bromobenzoic acid in the urine and bile of rats by inductively coupled plasma mass spectrometry.
