N-halo compounds nitrogen centered radicals, their chemistry and application in the living radical polymerization of MMA was written by Percec, V.;Grigoras, C.. And the article was included in Polymer Preprints (American Chemical Society, Division of Polymer Chemistry) in 2002.Name: 2-Chlorobenzo[d]isothiazol-3(2H)-one 1,1-dioxide This article mentions the following:
Our research group is elaborating new classes of universal initiators that are suitable for the design and synthesis of complex macromol. architectures. The N-centered radical chem. is not well understood except for some classic reactions. Here we report preliminary results on the use of various N-halogenated derivatives (Scheme 1) as initiators for the living radical polymerization (LRP) of Me methacrylate (MMA). LRP of MMA initiated with this new class of initiators based on N-halo derivatives was achieved with good results in spite of the initial expectation regarding their low reactivity towards electron-poor olefins. In the experiment, the researchers used many compounds, for example, 2-Chlorobenzo[d]isothiazol-3(2H)-one 1,1-dioxide (cas: 14070-51-0Name: 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. Chlorination modifies the physical properties of hydrocarbons in several ways. These compounds are typically denser than water due to the higher atomic weight of chlorine versus hydrogen.While alkyl bromides and iodides are more reactive, alkyl chlorides tend to be less expensive and more readily available. Alkyl chlorides readily undergo attack by nucleophiles.Name: 2-Chlorobenzo[d]isothiazol-3(2H)-one 1,1-dioxide
