Eosin-Y (EY)-mediated alkylsulfonyl cyanation of olefins was shown to afford alkylsulfonyl nitriles in good yields. On the basis of transient absorption spectroscopy, the reaction was shown to proceed via photoinduced electron transfer from 3EY* to an O-cyanated derivative of the photocatalyst, formed in situ, with generation of the corresponding sulfinate that is oxidized by EY•.+ into a sulfonyl
曙红-Y(EY)介导的烯烃烷基磺酰基氰化反应显示出可提供高收率的烷基磺酰基腈。根据瞬态吸收光谱法,反应通过光致电子从3 EY *转移至原位形成的光催化剂的O氰化衍生物而进行,并生成了被EY •氧化的亚磺酸盐。变成磺酰基。将后者加到烯烃上,然后进行自由基氰基基团转移,然后将腈与维持自由基链的RSO 2自由基一起提供。
