The article conveys some information:
An unprecedented electrochem. heterodifunctionalization of α-CF3 alkenes with benzenesulfonyl hydrazides was accomplished in this work, wherein a β-sulfonyl and a α-hydroxyl group were simultaneously incorporated across the olefinic double bond in a single operation. Consequently, a series of potentially medicinally valuable and densely functionalized α-trifluoromethyl-β-sulfonyl tertiary alcs. RSOOCH2C(OH)(CF3)R1 [R = i-Pr, Ph, 2-thienyl, etc.; R1 = Ph, 2-naphthyl, 3-thienyl, etc.] were assembled under mild conditions. Electrochem.-driven oxidative 1,2-difunctionalization of electron-deficient alkenes well obviates the need for oxidizing reagents, thus rendering this protocol more eco-friendly. In addition to this study using Thiophene-2-sulfonyl chloride, there are many other studies that have used Thiophene-2-sulfonyl chloride(cas: 16629-19-9Application In Synthesis of Thiophene-2-sulfonyl chloride) was used in this study.
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 In Synthesis of Thiophene-2-sulfonyl chloride
