perfluoroalkyl-tellurium linkages have been synthesized: CH3TeCF3, (CF3)2Te, CH3TeC2F5, (C2F5)2Te. These preparations were brought about by the photochemical interaction of (CH3)2Te and an appropriate perfluoroalkyl iodide in a vycor tube at 310 nm wavelength. The resulting mixture of tellurides, RfTeCH3 and (Rf)2Te in which Rf = CF3 or C2F5, cannot be separated by trap-to-trap distillation, but the relative amounts
合成了以下含有
全氟烷基-
碲键的新化合物:CH 3 TeCF 3,(CF 3)2 Te,CH 3 TeC 2 F 5,(C 2 F 5)2 Te。这些制备是通过(CH 3)2 Te和合适的
全氟烷基
碘在vycor管中在310 nm波长下的光
化学相互作用实现的。生成的
碲化物R f TeCH 3和(R f)2 Te的混合物,其中R f= CF 3或C 2 F 5,不能通过捕集捕集蒸馏分离,但是每种产物的相对量通过19 F NMR光谱法确定。将澄清的黄色
碲化物是空气稳定的,但是产率或者CF 3 H或C1 2 ˚F 5 H于碱性
水解。直到80°C时,没有观察到CH 3 Cl发生反应,但是在215°C时,CH 3 TeCF 3和(CF 3)2 Te的混合物与苄基
氯相互作用,生成3·4的C 6 H 5 CH 2 CF 3。分收益。
