The chemical properties of alicyclic heterocycles are similar to those of the corresponding chain compounds. Compound: [Ir(dtbbpy)(ppy)2]PF6, is researched, Molecular C40H40F6IrN4P, CAS is 676525-77-2, about The Tandem Photoredox Catalysis Mechanism of [Ir(ppy)2(dtb-bpy)]+ Enabling Access to Energy Demanding Organic Substrates, the main research direction is photoredox catalyst photoinduced electron transfer dehalogenation.Application of 676525-77-2.
We report the discovery of a tandem catalytic process to reduce energy demanding substrates, using the [Ir(ppy)2(dtb-bpy)]+ (1+) photocatalyst. The immediate products of photoinitiated electron transfer (PET) between 1+ and triethylamine (TEA) undergo subsequent reactions to generate a previously unknown, highly reducing species (2). Formation of 2 occurs via reduction and semisatn. of the ancillary dtb-bpy ligand, where the TEA radical cation serves as an effective hydrogen atom donor, confirmed by NMR, mass spectrometry, and deuterium labeling experiments Steady-state and time-resolved luminescence and absorption studies reveal that upon irradiation, 2 undergoes electron transfer or proton-coupled electron transfer (PCET) with a representative acceptor (N-(diphenylmethylene)-1-phenylmethanamine; S). Turnover of this new photocatalytic cycle occurs along with the reformation of 1+. We rationalize our observations by proposing the first example of a mechanistic pathway where two distinct yet interconnected photoredox cycles provide access to an extended reduction potential window capable of engaging a wide range of energy demanding and synthetically relevant organic substrates including aryl halides.
This literature about this compound(676525-77-2)Application of 676525-77-2has given us a lot of inspiration, and I hope that the research on this compound([Ir(dtbbpy)(ppy)2]PF6) can be further advanced. Maybe we can get more compounds in a similar way.
