New explortion of 2,4,5,6-Tetra(9H-carbazol-9-yl)isophthalonitrile

Because enzymes can increase reaction rates by enormous factors and tend to be very specific, Formula: C56H32N6, typically producing only a single product in quantitative yield, they are the focus of active research.you can also check out more blogs about 1416881-52-1

Chemistry is the experimental and theoretical study of materials on their properties at both the macroscopic and microscopic levels.In a patent， Formula: C56H32N6, Which mentioned a new discovery about 1416881-52-1

The combination of an organic photocatalyst [4CzIPN (1,2,3,5-tetrakis(carbazol-9-yl)-4,6 dicyanobenzene) or 5MeOCzBN (2,3,4,5,6-pentakis(3,6-dimethoxy-9 H-carbazol-9-yl)benzonitrile)], quinuclidine, and tetra-n-butylammonium phosphate (hydrogen-bonding catalyst) was employed for amide bond formations. The hydrogen-bonded OH group activated the adjacent C?H bond of alcohols towards hydrogen atom transfer (HAT) by a radical species. The quinuclidinium radical cation, generated through single-electron oxidation of quinuclidine by the photocatalyst, employed to abstract a hydrogen atom from the alpha-C?H bond of alcohols selectively due to a polarity effect-produced alpha-hydroxyalkyl radical, which subsequently converted to the corresponding aldehyde under aerobic conditions. Then the coupling of the aldehyde and an amine formed a hemiaminal intermediate that upon photocatalytic oxidation produced the amide.
