And the article was published in Synthesis in 2019. Name: 1,2-Diphenyldisulfane The author mentioned the following in the article:
A novel and convenient copper(I)-catalyzed thiolation of C-H bonds of pyrroles and indoles is developed for the synthesis of sulfenyl pyrroles I (RX= p-methylthiophenol, p-methoxythiophenol, p-nitrothiophrnol etc. Y= methylene, nitrogen) and indoles II (R= Hydrogen, 5-Me, 5-chloro etc. Y= methylene, nitrogen). Dual C-H thiolation reactions are observed for pyrroles. A wide range of pyrroles and indoles undergo the C-H thiolation smoothly with various disulfides and diselenides to generate the corresponding heteroaryl thioethers in moderate to excellent yields. In the experiment, the researchers used many compounds, for example, 1,2-Diphenyldisulfane(cas: 882-33-7Name: 1,2-Diphenyldisulfane)
1,2-Diphenyldisulfane(cas: 882-33-7) belongs to ethers.Ethers do have nonbonding electron pairs on their oxygen atoms, and they can form hydrogen bonds with other molecules (alcohols, amines, etc.) that have O―H or N―H bonds. The ability to form hydrogen bonds with other compounds makes ethers particularly good solvents for a wide variety of organic compounds and a surprisingly large number of inorganic compounds.Name: 1,2-Diphenyldisulfane
