A newly developed sulfonyl chlorides-based regioselective chloro-thiolation of alkenes has been disclosed, the reaction is compatible with a variety of functional groups and can be scaled up to the gram-scale with no loss in yield. The employment of readily available reactants, mild reaction conditions, and high regioselectivity makes this process very practical. Mechanistic studies revealed a possible free radical reaction pathway. The experimental part of the paper was very detailed, including the reaction process of 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
