Nickel-catalyzed direct formation of the C-S bonds of aryl sulfides from arylsulfonyl chlorides and aryl iodides using Mn as a reducing agent was written by Wang, Yang;Zhang, Xiaofeng;Liu, Haixiong;Chen, Hui;Huang, Deguang. And the article was included in Organic Chemistry Frontiers in 2017.SDS of cas: 5460-32-2 This article mentions the following:
Various unsym. aryl sulfides were synthesized by nickel-catalyzed C-S bond formation in good to excellent yields. The reactions employed arylsulfonyl chlorides as an aryl thiol source and Mn dust as a reducing agent. The scope and versatility of the method was successfully demonstrated with 42 examples. Mechanistic studies revealed the existence of an intermediate disulfide substance. A catalytic cycle was proposed including a three-step reduction by Mn for the achievement of the reaction, and Ni(0) and Ni(I) species were supposed to be involved in the reaction mechanism. In the experiment, the researchers used many compounds, for example, 4-Iodo-1,2-dimethoxybenzene (cas: 5460-32-2SDS of cas: 5460-32-2).
4-Iodo-1,2-dimethoxybenzene (cas: 5460-32-2) belongs to iodide derivatives. In general, organic iodides are light-sensitive and turn yellow during storage, owing to the formation of iodine. Polyiodoorganic compounds are sometimes employed as X-ray contrast agents, in fluoroscopy, a type of medical imaging. This application exploits the X-ray absorbing ability of the heavy iodine nucleus.SDS of cas: 5460-32-2
