Wang, Jin-Lin; Liu, Mei-Ling; Zou, Jian-Yu; Sun, Wen-Hui; Liu, Xue-Yuan published an article in 2022. The article was titled 《Copper-Catalyzed Aminoarylation of Alkenes via Aminyl Radical Addition and Aryl Migration》, and you may find the article in Organic Letters.SDS of cas: 16629-19-9 The information in the text is summarized as follows:
A new strategy for aminoarylation of alkenes by copper-catalyzed Smiles rearrangement using O-benzoylhydroxylamines as the amine reagent was described.. This method affords various β-amino amide derivatives possessing a quaternary carbon center with wide functional group tolerance and high regioselectivity. The mechanistic studies indicate that the transformation can involve aminyl radical intermediates under acid-free condition. The experimental part of the paper was very detailed, including the reaction process of Thiophene-2-sulfonyl chloride(cas: 16629-19-9SDS of cas: 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. SDS of cas: 16629-19-9
