摘要

建立了一种无过渡金属的统一合成方法，高效地构建了苯并噻吩并吡啶、苯并硒并吡啶和苯并telluropyridine。这种通用的方法促进了C-S， C-Se和C-Te键的形成，通过容易获得的二卤化吡啶双芳基与硫脲，单质硫，硒或碲的环化反应。值得注意的是，衍生产品显示出良好的潜力，可以作为苯并氯基苯融合吡啶结构的基石和有机光电应用的功能材料，特别是在有机发光二极管中。

A Unified Strategy for Transition-Metal-Free Synthesis of Benzothienopyridines, Benzoselenopyridines, and Benzotelluropyridines and Related Analogues

A transition-metal-free, unified synthetic approach has been developed for the efficient construction of benzothienopyridines, benzoselenopyridines, and benzotelluropyridines. This versatile methodology facilitates the formation of C–S, C–Se, and C–Te bonds through the cyclization reaction of readily available dihalogenated pyridyl biaryls with chalcogen sources (thiourea, elemental sulfur, selenium, or tellurium). Significantly, the derivatized products exhibit promising potential as building blocks for benzochalcogenophene-fused pyridine architectures and functional materials for organic optoelectronic applications, particularly in organic light-emitting diodes.

期刊介绍： Organic Letters invites original reports of fundamental research in all branches of the theory and practice of organic, physical organic, organometallic,medicinal, and bioorganic chemistry. Organic Letters provides rapid disclosure of the key elements of significant studies that are of interest to a large portion of the organic community. In selecting manuscripts for publication, the Editors place emphasis on the originality, quality and wide interest of the work. Authors should provide enough background information to place the new disclosure in context and to justify the rapid publication format. Back-to-back Letters will be considered. Full details should be reserved for an Article, which should appear in due course.
