novel, benign, and metal-free strategy for the difunctionalization of alkenes and alkynes using organophotoredox catalyst Eosin Y. The selective and controlled synthetic approach shows good substrate generality to afford sulfoxides, β-hydroxysulfoxides, and β-keto sulfides in high yield and excellent regioselectivity.
已经证明了使用环保空气 (O 2 ) 作为唯一氧化剂的可见光有机光氧化还原催化烯烃和炔烃与芳族和杂芳族硫醇的硫化。所建立的方法为使用有机光氧化还原催化剂 Eosin Y 对烯烃和炔烃进行双官能化提供了一种新颖、良性和无金属的策略。选择性和可控的合成方法显示出良好的底物通用性,可提供亚砜、β-羟基亚砜和 β-酮硫化物产率高,区域选择性好。
