Quality Control of 4,4-Dipyridyl Disulfide. The protonation of heteroatoms in aromatic heterocycles can be divided into two categories: lone pairs of electrons are in the aromatic ring conjugated system; and lone pairs of electrons do not participate. Compound: 4,4-Dipyridyl Disulfide, is researched, Molecular C10H8N2S2, CAS is 2645-22-9, about Metal-free, oxidative decarboxylation of aryldifluoroacetic acid with the formation of the ArS-CF2 bond. Author is Zhang, Yifang; Wang, Qian; Peng, Yi; Gong, Haiying; Chen, Hua; Deng, Hongmei; Hao, Jian; Wan, Wen.
A metal-free, oxidative decarboxylative reaction of aryldifluoroacetic acids ArCF2C(O)OH (Ar = 4-methoxylphenyl, 2,4,6-trifluoromethylphenyl, 1-naphthyl, etc.) with diaryl disulfides RSSR (R = Ph, thiophen-2-yl, benzo[d]thiazol-2-yl, etc.) or thiols R1SH (R1 = 4-methylphenyl, thiophen-2-yl, pyridin-2-yl, etc.) under mild reaction conditions has been developed. This is an efficient and straightforward radical cross-coupling method for the synthesis of diverse aryldifluoromethylthio ethers ArCF2SR or ArCF2SR1 in moderate to excellent yields.
After consulting a lot of data, we found that this compound(2645-22-9)Quality Control of 4,4-Dipyridyl Disulfide can be used in many types of reactions. And in most cases, this compound has more advantages.
