二(三氟甲基)碲是一种有机碲化合物,化学式为(CF3)2Te。

制备

二(三氟甲基)碲可由二甲基碲三氟碘甲烷混合后光解制得。[2]二(三氟甲基)汞四氯化碲的反应也能制得该化合物,但同时有副产物CF3TeCF2Cl和(CF2Cl)2Te。[3]

性质

二(三氟甲基)碲和溴在气相反应,生成(CF3)2TeBr2[1]

(CF3)2Te + Br2 → (CF3)2TeBr2

它和一些氟化剂(如一氟化氯等)反应,生成(CF3)2TeF2[4]其它氧化剂如Cl2、O2、ClONO2的反应可分别得到(CF3)2TeCl2、(CF3)2TeO和(CF3)2Te(ONO2)2[5]它和碘、硫、硒、磷、砷加热反应,生成相应的三氟甲基化合物E(CF3)n(n=1~3)。[6]
