6-tri-t-butylphenyl)phosphinoethynyl}-2-thienyl]octane with butyllithium followed by treatment with 1,2-dibromoethane afforded a new polymer containing 3,4-bis[(2,4,6-tri-t-butylphenyl)phosphinidene]-1,2-di(2-thienyl)cyclobutene units. The polymer was allowed to react with bis(benzonitrile)dichloropalladium to give the polymer complex. A Sonogashira coupling reaction between ethynyltrimethylsilane and 4-bromonitrobenzene
的1,8-双反应[5 - (2,4,6-三-吨丁基苯基)phosphinoethynyl} -2-噻吩基]辛烷与丁基锂,接着用1,2-二溴乙烷处理,得到含有3新的聚合物, 1,4-双[(2,4,6-三-吨丁基苯基)亚膦基] -1,2-二(2-噻吩基)环丁烯单元。使聚合物与双(苄腈)二氯钯反应,得到聚合物络合物。乙炔基三甲基硅烷和4-溴硝基苯之间的Sonogashira偶联反应在DMF中于100°C下进行,在聚合物配合物CuI和三乙胺存在下得到4-硝基(三甲基甲硅烷基乙炔基)苯。
