Chen, Si-Jie; Golden, Dung L.; Krska, Shane W.; Stahl, Shannon S. published an article about the compound: 2,6-Dichloropurine( cas:5451-40-1,SMILESS:C2=NC1=C(C(=NC(=N1)Cl)Cl)[NH]2 ).COA of Formula: C5H2Cl2N4. Aromatic heterocyclic compounds can be classified according to the number of heteroatoms or the size of the ring. The authors also want to convey more information about this compound (cas:5451-40-1) through the article.
A copper-catalyzed method that achieves site-selective cross-coupling of pyrazoles and other N-H heterocycles with substrates bearing (hetero)benzylic C-H bonds was reported. Excellent N-site selectivity was achieved, with preferred site controlled by identity of co-catalytic additives. This cross-coupling strategy featured broad scope for both N-H heterocycle and benzylic C-H coupling partners, enabling application of this method to complex mol. synthesis and medicinal chem.
After consulting a lot of data, we found that this compound(5451-40-1)COA of Formula: C5H2Cl2N4 can be used in many types of reactions. And in most cases, this compound has more advantages.
