《Copper(I)-Catalyzed Synthesis of Functionalized Indolizinones from Substituted Pyridine Homologated Ynones》 was written by Sahoo, Sushree Ranjan; Sarkar, Debayan; Henkel, Felix; Reuter, Hans. Quality Control of 1,2-Diphenyldisulfane And the article was included in Journal of Organic Chemistry in 2020. The article conveys some information:
An efficient two-component copper-catalyzed cyclization cascade approach toward highly functionalized indolizinone heterocycles has been developed from reactions of pyridine-, isoquinoline-, and quinoline ynones, via 5-exo-dig cyclization. The catalysis involves the activation by diorgano diselenide and diorgano disulfide and also their incorporation into the indolizinone core. In addition, the obtained substituted indolizinones were readily transformed into 1-(organochalcogenyl)indolizin-2-ols, which are important building blocks in organic synthesis. In addition to this study using 1,2-Diphenyldisulfane, there are many other studies that have used 1,2-Diphenyldisulfane(cas: 882-33-7Quality Control of 1,2-Diphenyldisulfane) was used in this study.
1,2-Diphenyldisulfane(cas: 882-33-7) belongs to ethers.The C-O bonds that comprise simple ethers are strong. Quality Control of 1,2-Diphenyldisulfane They are unreactive toward all but the strongest bases. Although generally of low chemical reactivity, they are more reactive than alkanes.
