dinaphtho[1,2-b:2′,1′-d]thiophenes and selenophenes, respectively. This is the first example of making two CS/Se bonds and a CC bond in a single step at room temperature and also demonstrates a useful method for the synthesis of both thiophenes and selenophenes on naphthalene. In the case of the reactions of elemental selenium, diselenides were also obtained along with dinaphtho[1,2-b:2′,1′-d]selenophenes
萘-1-磺酸二甲基酰胺用正丁基锂和元素硫或硒处理,分别得到二萘并[1,2-b:2',1'-d]噻吩和硒吩。这是在室温下一步合成两个 CS/Se 键和一个 CC 键的第一个例子,也展示了在萘上合成噻吩和硒酚的有用方法。在元素硒反应的情况下,二硒化物也与二萘并[1,2-b:2',1'-d]硒酚一起获得。二萘并[1,2-b:',1'-d]噻吩的结构通过X射线晶体学表征为代表性分子。© 2007 Wiley Periodicals, Inc. 杂原子化学 18:239–248, 2007; 在线发表于 Wiley InterScience (www.interscience.wiley.com)。DOI 10.1002/hc.20291
