α-arylation with sulfonylarenes having an azole, azine, and benzene nucleus. The α-arylation was scaled up using an electrolysis flow cell. Mechanistic studies show that anodic oxidation of an alkylamine with a sulfinate as a mediator followed by deprotonation gives an α-aminoalkyl radical, which undergoes homolytic aromatic substitution (HAS) on a sulfonylarene to give the corresponding α-arylalkylamine
烷基胺与磺酰芳烃的电化学 α-芳基化已经开发出来。这里,多种三烷基胺和芳基(二甲基)胺适用于与具有唑、吖嗪和苯核的磺酰芳烃的α-芳基化。使用电解流动池放大α-芳基化。机理研究表明,用亚磺酸盐作为介体对烷基胺进行阳极氧化,然后去质子化,得到α-氨基烷基自由基,该自由基在磺酰芳烃上进行均解芳族取代(HAS),得到相应的α-芳基烷基胺。
