在镍催化剂存在下,在包括炔、有机硼酸和磺酰氯的多组分反应中,以完全的区域和立体控制获得β,β-二取代乙烯基砜。该反应通过在温和的反应条件下原位产生的磺酰基自由基进行。
beta,beta-Disubstituted vinyl sulfones were obtained with complete regio- and stereocontrol in a multicomponent reaction involving alkynes, organoboronic acids, and sulfonyl chlorides in the presence of a nickel catalyst. The reaction proceeds via sulfonyl radicals generated in situ under mild reaction conditions.
