Name: 5,6-Dichloropyrazine-2,3-dicarbonitrile. Aromatic compounds can be divided into two categories: single heterocycles and fused heterocycles. Compound: 5,6-Dichloropyrazine-2,3-dicarbonitrile, is researched, Molecular C6Cl2N4, CAS is 56413-95-7, about A Multifunctional Reagent Designed for the Site-Selective Amination of Pyridines. Author is Fier, Patrick S.; Kim, Suhong; Cohen, Ryan D..
The development of a multifunctional reagent for the direct conversion of pyridines to Boc-protected 2-aminopyridines such as I [R = H, 3-Br, 4-Ph, etc.] with exquisite site selectivity and chemoselectivity was reported. The novel reagent was prepared on 200g scale in a single step, reacted in title reaction under mild conditions without precautions toward air or moisture, and is tolerant of nearly all common functionality. Exptl. and in situ spectroscopic monitoring techniques provided detailed insights and unexpected findings for the unique reaction mechanism.
After consulting a lot of data, we found that this compound(56413-95-7)Name: 5,6-Dichloropyrazine-2,3-dicarbonitrile can be used in many types of reactions. And in most cases, this compound has more advantages.
