of dimethyl sulfoxide has been developed. This study realizes a new, conceptually novel technology for convenient construction of a variety of α-aryl-γ-methylsulfinyl ketones in good-to-excellent yields with the synergistic interactions of visible light irradiation, organic fluorophores 4CzIPN, and hypervalent iodine(III) reagent under transition-metal free conditions. A remarkable kinetic isotope effect
已开发出具有二甲基亚砜的α-C(sp 3)-H键的未活化烯烃的无金属氧化基团的1,2-烷基芳基化反应。这项研究实现了一种概念上新颖的新技术,该技术可方便地以良好至优异的产率构建各种α-芳基-γ-甲基亚磺酰基酮,并且具有可见光照射,有机荧光团4CzIPN和高价碘(III)的协同相互作用。试剂在无过渡金属的条件下使用。观察到了显着的动力学同位素效应,这有助于深入了解反应的机理。
