In 2019,Nature Communications included an article by Zhu, Shengqing; Qin, Jian; Wang, Fang; Li, Huan; Chu, Lingling. COA of Formula: C6H4N2. The article was titled 《Photoredox-catalyzed branch-selective pyridylation of alkenes for the expedient synthesis of Triprolidine》. The information in the text is summarized as follows:
A catalytic, branch-selective pyridylation of alkenes via a sulfinate assisted photoredox catalysis was reported. This reaction proceeded through a sequential radical addition/coupling/elimination, by utilizing readily available sodium sulfinates as reusable radical precursors as well as traceless elimination groups. This versatile protocol allows for the installation of important vinylpyridines with complete branched selectivity under mild conditions. Furthermore, this catalytic manifold was successfully applied to the expedient synthesis of Triprolidine. In the experiment, the researchers used 4-Cyanopyridine(cas: 100-48-1COA of Formula: C6H4N2)
4-Cyanopyridine(cas: 100-48-1) belongs to pyridine. In industry and in the lab, pyridine is used as a reaction solvent, particularly when its basicity is useful, and as a starting material for synthesizing some herbicides, fungicides, and antiseptics.COA of Formula: C6H4N2
