functionalized dichlorinated vinyl sulfones. This method features excellent regio- and stereoselectivities, good functional group compatibility, as well as mild reaction conditions. Mechanistic studies suggest that the reaction goes through sequential syn-chloropalladation, alkene insertion, and C(sp3)–Cl bond formation processes, and the sulfonyl group is crucial to the stereoselectivity control of the reaction
已经描述了炔基砜与烯烃的钯催化偶联反应,这为各种官能化二氯化乙烯基砜提供了有效和实用的途径。该方法具有优异的区域和立体选择性、良好的官能团相容性以及温和的反应条件。机理研究表明,该反应经历了顺序的顺式氯钯化、烯烃插入和 C(sp 3 )-Cl 键形成过程,磺酰基对反应的立体选择性控制至关重要。
