In 2019,Journal of the American Chemical Society included an article by Tanaka, Keita; Ewing, William R.; Yu, Jin-Quan. Synthetic Route of C6H7Br2N. The article was titled 《Hemilabile Benzyl Ether Enables γ-C(sp3)-H Carbonylation and Olefination of Alcohols》. The information in the text is summarized as follows:
Pd-catalyzed C(sp3)-H activation of alc. typically shows β-selectivity due to the required distance between the chelating atom in the attached directing group and the targeted C-H bonds. Herein the authors report the design of a hemilabile directing group which exploits the chelation of a readily removable benzyl ether moiety to direct γ- or δ-C-H carbonylation and olefination of alcs. The utility of this approach is also demonstrated in the late-stage C-H functionalization of β-estradiol to rapidly prepare desired analogs that required multi-step syntheses with classical methods. In addition to this study using 2-(Bromomethyl)pyridine hydrobromide, there are many other studies that have used 2-(Bromomethyl)pyridine hydrobromide(cas: 31106-82-8Synthetic Route of C6H7Br2N) was used in this study.
2-(Bromomethyl)pyridine hydrobromide(cas: 31106-82-8) belongs to pyridine. Pyridine’s structure is isoelectronic with that of benzene, but its properties are quite different. Pyridine is completely miscible with water, whereas benzene is only slightly soluble. Like all hydrocarbons, benzene is neutral (in the acid–base sense), but because of its nitrogen atom, pyridine is a weak base.Synthetic Route of C6H7Br2N
