Aryl tellurium trichlorides and tribromides undergo condensation reactions with acetone, acetophenone, N-dimethylaniline and resorcinol, giving rise to aryl tellurium dihalides. Aryl tellurium triiodides are not reactive. The dihalides derived from N-dimethylaniline and resorcinol undergo ionic interchange reactions with halide ions. When treated with reducing agents the dihalides derived from N-dimethylaniline
芳基碲三氯化物和三溴化物与丙酮,苯乙酮,N-二甲基苯胺和间苯二酚进行缩合反应,生成芳基碲二卤化物。芳基三碘化碲不具有反应性。衍生自N-二甲基苯胺和间苯二酚的二卤化物与卤离子进行离子交换反应。当用还原剂处理时,衍生自N-二甲基苯胺的二卤化物被还原成相应的碲化物,而其他二卤化物被裂解成二芳基-二碲化物。
