So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic.Wallentin, Carl-Johan; Nguyen, John D.; Finkbeiner, Peter; Stephenson, Corey R. J. researched the compound: [Ir(dtbbpy)(ppy)2]PF6( cas:676525-77-2 ).Safety of [Ir(dtbbpy)(ppy)2]PF6.They published the article 《Visible Light-Mediated Atom Transfer Radical Addition via Oxidative and Reductive Quenching of Photocatalysts》 about this compound( cas:676525-77-2 ) in Journal of the American Chemical Society. Keywords: visible atom transfer radical addition oxidative reductive quenching photocatalyst. We’ll tell you more about this compound (cas:676525-77-2).
Herein, the development of visible light-mediated atom transfer radical addition (ATRA) of haloalkanes onto alkenes and alkynes using the reductive and oxidative quenching of [Ir{dF(CF3)ppy}2(dtbbpy)]PF6 and [Ru(bpy)3]Cl2 is presented. Initial studies indicated that the oxidative quenching of photocatalysts could effectively be used for ATRA, and since that report, the protocol was expanded by broadening the scope of the reaction in terms of the photocatalysts, substrates, and solvents. Further modifications of the reaction conditions allowed for the efficient ATRA of perfluoroalkyl iodides onto alkenes and alkynes using the reductive quenching cycle of [Ru(bpy)3]Cl2 with sodium ascorbate as the sacrificial electron donor. These results signify the complementary nature of the oxidative and reductive quenching pathways of photocatalysts and the ability to predictably direct reaction outcome through modification of the reaction conditions.
