halides in CHCl3. These compounds, which contain the ArTeX−4 anion, may be also prepared from aryltellurium trihalides and aqueous halogen hydride solutions. The phosphonium derivatives can be considered as potential precursors of tellurophosphoranes for Wittig reactions. Halogen exchange reactions allow the interconversion of the complex anions. The ionic nature of the compounds is supported by ion exchange
四卤代芳基碲酸酯(IV)是通过将三卤代芳基碲与phospho,对苯二甲基ium和碲化卤化物在CHCl 3中回流制备的。这些包含ArTeX - 4阴离子的化合物也可以由芳基碲三卤化物和卤化氢水溶液制备。derivatives衍生物可被认为是维蒂希反应中碲铝膦的潜在前体。卤素交换反应允许复合阴离子的相互转化。通过利用离子交换树脂的离子交换反应和电导测量来支持化合物的离子性质。远红外和拉曼光谱数据表明ArTeX - 4阴离子呈方形锥体构型。
