selenide construction through S–I and Se–I exchange without transition metal assistance. Elemental sulfur and selenium served as the chalcogen source. Diarylannulated sulfides were systematically achieved from a five- to eight-membered ring. A trisulfur radical anion 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)。
