Liu, Zhao-Yang; Peng, Wei-Yu; Akram, Waseem; Lai, Jia-Wei; Zhang, Hao; Liu, Hai-Yang published their research in Heterocycles in 2021. The article was titled 《Copper corrole catalyzed esterification of C(sp3)-H with carboxylic acids via cross-dehydrogenative coupling reaction》.Name: 4-Bromobenzoic acid The article contains the following contents:
Copper corrole complex was firstly used as catalyst for oxidative esterification of un-reactive C(sp3)-H bond of cyclic ether and carboxylic acid via cross-dehydrogenative coupling (CDC) reaction using di-tert-Bu peroxide (DTBP) as oxidant. A wide range of carboxylic acids can react with cyclic ether with good to excellent yields, showing copper corrole is a new kind of promising catalyst for CDC reaction. Under gram-level test, the turnover number (TON) may achieve 8400 with 84% yield at only 0.01% catalyst loading, demonstrating its practical uses. The experimental process involved the reaction of 4-Bromobenzoic acid(cas: 586-76-5Name: 4-Bromobenzoic acid)
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.Name: 4-Bromobenzoic acid 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.
