A straightforward protocol for diarylannulated sulfone construction is efficiently established via SO2/I exchange of iodonium(III) salts. Readily available inorganic Na2S2O5 was served as a safe and convenient SO2 surrogate. Diverse functionalized diarylannulated sulfones were smoothly achieved in good to excellent yields with great functional group compatibility. Organic light emitting diodes (OLEDs)
通过二碘鎓(III)盐的SO 2 / I交换有效地建立了用于二芳基环氧基砜构建的简单方法。随时可用的无机Na 2 S 2 O 5作为安全便捷的SO 2替代。顺利实现了多种功能化的二芳基环化砜,具有良好的收率和优异的收率,并且具有很好的官能团相容性。随后通过该方法以克为单位建立有机发光二极管(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-共轭桥基序的不对称共轭体系,该体系基本传达了半导体材料分子中的电子迁移率。

selenide construction through S–I and Se–I exchange without transition metal assistance. Elementalsulfur and selenium served as the chalcogen source. Diarylannulated sulfides were systematically achieved from a five- to eight-membered ring. A trisulfurradicalanion was demonstrated as the initiator for this radical process via electron paramagnetic resonance (EPR) study. OFET molecules [1]benzothieno[3
在没有过渡金属协助的情况下,通过S–I和Se–I交换,可以轻松,直接地建立二芳基环化硫化物和硒化物的制备方法。元素硫和硒用作硫族元素来源。从五元至八元环系统地制得二芳基环化的硫化物。通过电子顺磁共振(EPR)研究,三硫自由基阴离子被证明是该自由基过程的引发剂。高效地建立了OFET分子[1]苯并噻吩并[3,2- b ] [1]苯并噻吩(BTBT)和[1]苯并噻吩并[3,2- b ] [1]苯并硒吩(BTBS)。
