The synthesis and characterization of low-valent organoselenium and tellurium derivatives of hexabromododecahydrotriphenylene has been attempted. The reaction of hexabromododecahydrotriphenylene with in situ generated disodium dichalcogenides (Na2E2; E = Se, Te) afforded insoluble chalcododecahydrotriphenylene derivatives, 20, 21 respectively. Attempted aromatization of 20 and 21 usingDDQ (2, 3-dichloro-5
已经尝试了六溴十二碳三苯并三苯的低价有机硒和碲衍生物的合成和表征。hexabromododecahydrotriphenylene与反应原位产生的二硫属化物二钠(钠2 ë 2 ; E =硒,碲),得到不溶性chalcododecahydrotriphenylene衍生物,20,21分别。使用DDQ(2,3-二氯-5,6-二氰基-1,4-苯醌)作为氧化剂尝试20和21的芳构化得到共晶体。六硒代苯基衍生物22和六硒代氰酸酯衍生物23通过以下反应合成:原位生成的芳基硒化钠/硒化钾与六溴十二碳三苯并苯。这些化合物通过常用的光谱工具表征,少数通过单晶X射线晶体学研究表征。 Organoselenide 20是由反应合成1,4,5,8,9,12与hexabromododecahydrotriphenylene原位生成的Na 2硒2在室温下。芳香化20种化合物24和26。
