Liu, Liang’s team published research in Journal of Organic Chemistry in 2020 | CAS: 94928-86-6

fac-Tris(2-phenylpyridine)iridium(cas: 94928-86-6) 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.Application of 94928-86-6

《Redox-neutral photocatalytic radical cascade cyclization for the synthesis of CH2CN/CF2COOEt/CF3 containing benzo[4,5]imidazo[2,1-a]isoquinolin-6(5H)-one derivatives》 was published in Journal of Organic Chemistry in 2020. These research results belong to Liu, Liang; Yang, De-Yong; He, Yan-Hong; Guan, Zhi. Application of 94928-86-6 The article mentions the following:

A novel method for the synthesis of benzo[4,5]imidazo[2,1-a]isoquinoline derivatives I (R = CH2CN, CF3, CF2COOEt; R1 = H, 9,10-diMe; R2 = H, 3-Me, 3-Cl, etc.) via visible-light-induced radical cascade cyclization is described. By using N-methacryloyl-2-phenylbenzimidazoles and diverse radical precursors, various benzo[4,5]imidazo[2,1-a]isoquinoline derivatives containing CH2CN/CF2COOEt/CF3 can be formed in good to excellent yields under mild reaction conditions. The method exhibits good functional group tolerance and a wide range of substrate scope.fac-Tris(2-phenylpyridine)iridium(cas: 94928-86-6Application of 94928-86-6) was used in this study.
