Compound: [Ir(dtbbpy)(ppy)2]PF6, is researched, Molecular C40H40F6IrN4P, CAS is 676525-77-2, about Oxygen Switch in Visible-Light Photoredox Catalysis: Radical Additions and Cyclizations and Unexpected C-C-Bond Cleavage Reactions, the main research direction is oxygen switch visible photoredox catalysis radical addition cyclization cleavage.HPLC of Formula: 676525-77-2.
Visible light photoredox catalyzed inter- and intramol. C-H functionalization reactions of tertiary amines have been developed. Oxygen was found to act as chem. switch to trigger two different reaction pathways and to obtain two different types of products from the same starting material. In the absence of oxygen, the intermol. addition of N,N-dimethylanilines to electron-deficient alkenes provided γ-amino nitriles in good to high yields. In the presence of oxygen, a radical addition/cyclization reaction occurred which resulted in the formation of tetrahydroquinoline derivatives in good yields under mild reaction conditions. The intramol. version of the radical addition led to the unexpected formation of indole-3-carboxaldehyde derivatives Mechanistic investigations of this reaction cascade uncovered a new photoredox catalyzed C-C bond cleavage reaction.
Although many compounds look similar to this compound(676525-77-2)HPLC of Formula: 676525-77-2, numerous studies have shown that 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), has unique advantages.
