Epoxy compounds usually have stronger nucleophilic ability, because the alkyl group on the oxygen atom makes the bond angle smaller, which makes the lone pair of electrons react more dissimilarly with the electron-deficient system. Compound: [Ir(dtbbpy)(ppy)2]PF6, is researched, Molecular C40H40F6IrN4P, CAS is 676525-77-2, about A photoredox catalyzed radical-radical coupling reaction: facile access to multi-substituted nitrogen heterocycles.Safety of [Ir(dtbbpy)(ppy)2]PF6.
Visible light induced photoredox catalysis is an efficient method for radical activation. Herein, we report the photoredox catalysis involving an intramol. radical-radical coupling reaction that proceeds through a biradical intermediate. This protocol represents a new synthetic route to construct multi-substituted N-heterocycles, e.g. I. Four, five and six-membered N-heterocyclic structures with a quaternary carbon center are accessible under mild conditions.
There is still a lot of research devoted to this compound(SMILES：[F-][P+5]([F-])([F-])([F-])([F-])[F-].CC(C)(C1=CC=[N]([Ir+3]23([C-]4=CC=CC=C4C5=CC=CC=[N]25)([C-]6=CC=CC=C6C7=CC=CC=[N]37)[N]8=CC=C(C(C)(C)C)C=C98)C9=C1)C)Safety of [Ir(dtbbpy)(ppy)2]PF6, and with the development of science, more effects of this compound(676525-77-2) can be discovered.
