摘要/Abstract

含硫有机化合物广泛应用于有机合成、医药、农药和功能材料等领域中, 发展绿色、温和、高效的有机硫化合物的合成方法具有重要意义. 作为理想的绿色氧化剂, 氧气可直接引发一些含硫化合物为硫中心自由基, 其参与的反应为构建S—S、P—S和C—S键提供了新途径. 该方法可避免使用毒性试剂、过渡金属和强氧化剂等, 而且反应条件温和. 依据反应类型的不同, 对近年来氧气引发的硫中心自由基参与的构建S—S、P—S和C—S键研究进展进行介绍.

Sulfur-containing organic compounds have been widely used in organic synthesis, pharmaceuticals, pesticides and functional materials. Thus, the development of green, mild and highly efficient methodologies for the synthesis of organosulfur compounds is of great importance. Some sulfur-containing compounds can be directly initiated by O₂ as the ideal green oxidant to generate sulfur-centered radicals, and the corresponding radical reactions provide a novel approach to the construction of S—S, P—S and C—S bonds. These reactions can be performed under mild conditions without the use of toxic reagents, transition metals and strong oxidants. In this review, the recent progress in the construction of S—S, P—S and C—S bonds involving O₂-initiated sulfur-centered radicals is introduced on the basis of different reaction types.
Key words: oxygen, sulfur-centered radicals, organosulfur compounds, radical reactions
