Safety of [Ir(dtbbpy)(ppy)2]PF6. The fused heterocycle is formed by combining a benzene ring with a single heterocycle, or two or more single heterocycles. Compound: [Ir(dtbbpy)(ppy)2]PF6, is researched, Molecular C40H40F6IrN4P, CAS is 676525-77-2, about Alkene functionalization for the stereospecific synthesis of substituted aziridines by visible-light photoredox catalysis. Author is Yu, Wan-Lei; Chen, Jian-Qiang; Wei, Yun-Long; Wang, Zhu-Yin; Xu, Peng-Fei.
A novel strategy involving visible-light-induced functionalization of alkenes for the synthesis of substituted aziridines such as I [R = Me, CH2Br, Ph, etc.; Ar = Ph, 4-BrC6H4, 2-naphthyl, etc.; Ar1 = Ph, 4-F3CC6H4, 3,4-Cl2-C6H3, etc.] was developed. The readily prepared N-protected 1-aminopyridinium salts were used for the generation of N-centered radicals. This approach allowed the synthesis of aziridines bearing various functional groups with excellent diastereoselectivity under mild conditions. Moreover, this protocol was successfully applied to prepare structurally diverse nitrogen-containing frameworks.
