Yang, Cai-Yun; Li, Xia; Liu, Bo; Huang, Guo-Li published an article in 2021. The article was titled 《I2-Promoted Direct C-H Sulfenylation of Isoquinolin-1(2H)-ones with Sulfonyl Chlorides》, and you may find the article in European Journal of Organic Chemistry.Application of 98-60-2 The information in the text is summarized as follows:
A simple, efficient, and green method for the iodine-promoted regioselective C-4 sulfenylation of isoquinolin-1(2H)-ones using com. available aryl sulfonyl chlorides as the sulfur source was described under metal- and solvent-free conditions. The reaction proceeded smoothly under simple conditions to obtain 4-arylthioisoquinolin-1(2H)-ones, e.g. I, in moderate to good yields, and showed high regioselectivity, broad substrate scope, and good functional group tolerance. A radical reaction mechanism involving ArS. radicals as key intermediates is proposed for the present transformation. In the part of experimental materials, we found many familiar compounds, such as 4-Chlorobenzenesulfonyl chloride(cas: 98-60-2Application of 98-60-2)
4-Chlorobenzenesulfonyl chloride(cas: 98-60-2) belongs to organochlorine compounds. Alkanes and aryl alkanes may be chlorinated under free radical conditions, with UV light. However, the extent of chlorination is difficult to control. Aryl chlorides may be prepared by the Friedel-Crafts halogenation, using chlorine and a Lewis acid catalyst.Application of 98-60-2
