A copper-catalyzed cross-dehydrogenative C–H/N–H coupling has been devised to access a series of N-arylated sulfoximines in high yield from 8-aminoquinoline-derived benzamides and sulfoximines. The reaction is scalable, and mechanistic studies favor the involvement of an organometallic pathway, where C–H bond cleavage is presumed to be the kinetically relevant step. The utility of sulfoximine-coupled
已经设计了铜催化的交叉脱氢C–H / N–H偶联物,以从8-氨基喹啉衍生的苯甲酰胺和亚砜肟类中高收率获得一系列N-芳基化亚砜基。该反应是可扩展的,并且机理研究支持有机金属途径的参与,其中CH键的断裂被认为是动力学上相关的步骤。通过镍催化的苄基醇的无受体脱氢烯化反应显示出了亚砜亚胺偶联的苯甲酰胺的效用。
