A copper-catalyzedcross-dehydrogenativeC–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

most investigated electrochemical approaches for converting thermodynamically inert carbon dioxide (CO2) into value-added carboxylic acids. By converting organic halides into their sulfone derivatives, we have developed a highly efficient electrochemical desulfonylative carboxylation protocol. Such a strategy takes advantage of CO2 as the abundant C1 building block for the facile preparation of multifunctionalized
有机卤化物的电羧化是将热力学惰性二氧化碳 (CO 2 ) 转化为增值羧酸的最受研究的电化学方法之一。通过将有机卤化物转化为其砜衍生物,我们开发了一种高效的电化学脱磺酰羧化方案。这种策略利用 CO 2作为丰富的 C1 结构单元,在温和的反应条件下轻松制备多功能羧酸,包括非甾体抗炎药布洛芬。
