A straightforward protocol for diarylannulated sulfone construction is efficiently established via SO/I exchange of iodonium(III) salts. Readily available inorganic NaSO was served as a safe and convenient SO surrogate. Diverse functionalized diarylannulated sulfones were smoothly achieved in good to excellent yields with great functional group compatibility. Organic light emitting diodes (OLEDs) material molecules were subsequently established via this method in gram scale. The unsymmetrical conjugated systems with donor-acceptor groups and π-conjugation bridges motifs, which substantially communicate electron mobility in semiconductor material molecules, were successfully afforded under the facile conditions of the exchange strategy.
通过碘鎓(III)盐的 SO/I 交换，高效建立了一种直链 diarylannulated 砜的构建方法。易得的无机 NaSO 被用作安全且方便的 SO 替代物。各种功能化的二芳基 annulated 砜以良好至优异的收率顺利合成，具有很好的官能团相容性。随后，通过该方法在克级规模上建立了有机发光二极管（OLED）材料分子。在交换策略的简便条件下，成功提供了具有供体-受体基团和π共轭桥模体的不对称共轭体系，这些体系在半导体材料分子中有效地传递电子迁移率。
