Visible-light promoted intermolecular halofunctionalization of alkenes with N-halogen saccharins was written by Song, Lu;Luo, Sanzhong;Cheng, Jin-Pei. And the article was included in Organic Chemistry Frontiers in 2016.Application In Synthesis of 2-Chlorobenzo[d]isothiazol-3(2H)-one 1,1-dioxide This article mentions the following:
A simple and efficient visible-light promoted intermol. haloamination and haloetherification of alkenes using N-halosaccharin as the halogen and nitrogen/oxygen source (halo = Br, Cl) was reported. The reaction was applied to a very broad range of alkenes to generate haloamines and haloethers with high isolated yields. With DBU as the base, metal-free C-H amination of aryl olefins was achieved with good yields. In the experiment, the researchers used many compounds, for example, 2-Chlorobenzo[d]isothiazol-3(2H)-one 1,1-dioxide (cas: 14070-51-0Application In Synthesis of 2-Chlorobenzo[d]isothiazol-3(2H)-one 1,1-dioxide).
2-Chlorobenzo[d]isothiazol-3(2H)-one 1,1-dioxide (cas: 14070-51-0) belongs to organic chlorides. Chlorinated organic compounds are found in nearly every class of biomolecules and natural products including alkaloids, terpenes, amino acids, flavonoids, steroids, and fatty acids. Alkyl chlorides readily react with amines to give substituted amines. Alkyl chlorides are substituted by softer halides such as the iodide in the Finkelstein reaction.Application In Synthesis of 2-Chlorobenzo[d]isothiazol-3(2H)-one 1,1-dioxide
