《C- to N-Center Remote Heteroaryl Migration via Electrochemical Initiation of N Radical by Organic Catalyst》 was written by Liu, Chengkou; Jiang, Qiang; Lin, Yang; Fang, Zheng; Guo, Kai. Electric Literature of C4H3ClO2S2 And the article was included in Organic Letters in 2020. The article conveys some information:
Herein an exogenous oxidant- and metal-free electrochem. heteroaryl migration triggered by N radicals to construct new N-C bonds was developed. This methodol. features a high atom economy and utilization rate of energy, and it is insensitive to water and air. Moreover, a user-friendly undivided cell was employed. The use of an organic catalyst makes it more efficient, green, and practical. In the experiment, the researchers used Thiophene-2-sulfonyl chloride(cas: 16629-19-9Electric Literature of C4H3ClO2S2)
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. Electric Literature of C4H3ClO2S2
