《Metal-Free Electrochemical Coupling of Vinyl Azides: Synthesis of Phenanthridines and β-Ketosulfones》 was written by Li, Guodong; Kong, Xianqiang; Liang, Qi; Lin, Long; Yu, Ke; Xu, Bo; Chen, Qianjin. Recommanded Product: Thiophene-2-sulfonyl chloride And the article was included in European Journal of Organic Chemistry in 2020. The article conveys some information:
The authors reported an efficient and environmentally benign electrochem. synthesis of phenanthridines by oxidative coupling of vinyl azides with sodium azide or benzenesulfonyl hydrazides, for the first time. The reaction conditions are mild, and no addnl. metal-catalyst or exogenous oxidants are needed. The protocol has broad substrate scope and high functional group tolerance. Furthermore, this green electrochem. procedure can be readily extended to the synthesis of β-ketosulfones. Gram scale reactions further demonstrate the practicability. In the experiment, the researchers used many compounds, for example, Thiophene-2-sulfonyl chloride(cas: 16629-19-9Recommanded Product: Thiophene-2-sulfonyl chloride)
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. Recommanded Product: Thiophene-2-sulfonyl chloride
