Liu, Lixia; Wang, Chengming published their research in Reaction Chemistry & Engineering in 2021. The article was titled 《Copper-catalyzed redox-neutral regioselective chlorosulfonylation of vinylarenes》.Application of 16629-19-9 The article contains the following contents:
A copper-catalyzed redox-neutral, regioselective aromatic alkene chlorosulfonylation reaction has been developed. This protocol features simple procedure, easily accessible materials and good functional group tolerance. Moreover, it could be amplified to a gram scale and smoothly applied to the late-stage modification of bioactive mol. derivatives In the experiment, the researchers used many compounds, for example, Thiophene-2-sulfonyl chloride(cas: 16629-19-9Application of 16629-19-9)
Thiophene-2-sulfonyl chloride(cas: 16629-19-9) is a member of sulfonyl chlorides. Sulfonyl chlorides are reactive sulfonic acid derivatives similar in properties and reactivity to acid chlorides of carboxylates. The sulfonic acid group, however, is a highly hindered molecule, containing a tetrahedral configuration of substituents. Application of 16629-19-9
