In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Visible-Light-Triggered Directly Reductive Arylation of Carbonyl/Iminyl Derivatives through Photocatalytic PCET, published in 2017-07-21, which mentions a compound: 676525-77-2, mainly applied to nitrile carbonyl reductive arylation imine photocatalyst radical; secondary alc amine preparation, Recommanded Product: [Ir(dtbbpy)(ppy)2]PF6.
The first visible-light-mediated radical-radical cross-coupling strategy that enables the direct arylation of carbonyl/iminyl derivatives in the presence of Et3N has been realized. Such an atom-economical protocol furnishes a broad scope of arylation products such as secondary/tertiary alcs. and amines via a PCET process that facilitates the challenging reduction of C=X (X = O, N). Mechanistic investigation indicates two photocatalytic redox cycles were involved in the process, and Et3N was proved to serve as a dual reductant and proton donor. Moreover, the isolated byproducts and controlled experiments could be considered as powerful supporting evidence for our hypothesis.
Although many compounds look similar to this compound(676525-77-2)Recommanded Product: [Ir(dtbbpy)(ppy)2]PF6, 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.
