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.
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
