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-driven oxidation of 1,3-dicarbonyl compounds via catalytic disproportionation of TEMPO by photoredox catalysis, published in 2012-09-05, which mentions a compound: 676525-77-2, mainly applied to dicarbonyl compound oxyamination oxidative dimerization photoredox catalyst visible light, Product Details of 676525-77-2.
Visible light irradiation of a mixture of 1,3-dicarbonyls and 2,2,6,6-tetramethylpiperidine 1-oxyl (TEMPO) in the presence of photoredox catalysts, [Ru(bpy)3]2+ and [Ir(ppy)2(dtbbpy)]+ (bpy: 2,2′-bipyridine, ppy: 2-phenylpyridine, dtbbpy: 4,4′-di-tert-butyl-2,2′-bipyridine), afforded two types of oxidized products, i.e., α-oxyaminated products from acyclic 1,3-dicarbonyls and oxidatively dimerized products from cyclic 1,3-dicarbonyls. The Ir catalyst turned out to be more active than the Ru catalyst. This is a new photocatalytic oxidation of 1,3-dicarbonyls based on a single-electron-transfer process mediated by excited photoredox catalysts.
Here is just a brief introduction to this compound(676525-77-2)Product Details of 676525-77-2, more information about the compound([Ir(dtbbpy)(ppy)2]PF6) is in the article, you can click the link below.
