Zhao, Yu; Zhang, Chenhao; Chin, Kek Foo; Pytela, Oldrich; Wei, Guo; Liu, Hongjun; Bures, Filip; Jiang, Zhiyong published the article 《Dicyanopyrazine-derived push-pull chromophores for highly efficient photoredox catalysis》. Keywords: dicyanopyrazine photoredox catalyst optical gap absorption density functional theory.They researched the compound: 5,6-Dichloropyrazine-2,3-dicarbonitrile( cas:56413-95-7 ).Synthetic Route of C6Cl2N4. Aromatic heterocyclic compounds can be divided into two categories: single heterocyclic and fused heterocyclic. In addition, there is a lot of other information about this compound (cas:56413-95-7) here.
Here, we report dicyanopyrazine (DPZ)-derived push-pull chromophores, easily prepared and tunable organic compounds, as new kinds of photoredox catalysts. In particular, the DPZ derivative H, containing 2-methoxythienyl as electron-donating moiety, exhibits a broad absorption of visible light with an absorption edge up to 500 nm and excellent redox properties, and has been demonstrated as a desirably active and efficient photoredox catalyst in four challenging kinds of photoredox reactions. The amount of catalyst in most reactions is less than 0.1 mol% and even 0.01 mol%, representing the lowest catalyst loading in the current photoredox organocatalysis.
This literature about this compound(56413-95-7)Synthetic Route of C6Cl2N4has given us a lot of inspiration, and I hope that the research on this compound(5,6-Dichloropyrazine-2,3-dicarbonitrile) can be further advanced. Maybe we can get more compounds in a similar way.
