2,2,2-Trifluoroethyl aryl tellurides, viz; C6H5TeCH2CF3 and p-CH3C6H4TeCH2CF3 are prepared in high yields by reacting alkylating agent (2,2,2-trifluoroethyl tosylate or 2,2,2-trifluoroethyl iodide) with aryl tellurolate anion generated . These tellurides have been converted to their corresponding tellurium dichlorides which on further treatment with NaOCH2CF3 in CF3CH2OH medium gave the corresponding
2,2,2-三氟乙基芳基碲化物,即;通过使烷基化剂(2,2,2-三氟乙基甲苯磺酸盐或2,2,2-三氟乙基碘化物)与烷基化剂反应,可以高收率制备C 6 H 5 TeCH 2 CF 3和对-CH 3 C 6 H 4 TeCH 2 CF 3。生成碲酸芳芳酯阴离子。这些碲化物已转化为其相应的二氯化碲,将其进一步用NaOCH 2 CF 3在CF 3 CH 2中处理在OH介质中得到相应的双(2,2,2-三氟乙氧化物)。这些化合物已通过元素分析,IR,1 H和19 F NMR和质谱表征。
