Syntheses and molecular structures of organo-tellurium(IV) halides trans-[(Ph2Te)(μ-Cl)2]n, cis-[(Ph2Te)(μ-Cl)2]n, [(p-MeC6H4)2TeBr2], and [{(p-MeC6H4)2TeBr}2(μ-O)]

Treatment of Ph2Te with aqueous hydrogen chloride under air in refluxing THF gave trans-[(Ph2Te)(μ-Cl)2]n (1), whereas interaction of Ph2Te with ammonium chloride under similar condition afforded cis-[(Ph2Te)(μ-Cl)2]n (2). Reaction of (p-MeC6H4)2Te and bromine in refluxing THF resulted in formation of a discrete complex [(p-MeC6H4)2TeBr2] (3) with a step-like tetrameric structure, which further reacted with sodium hydroxide in refluxing THF to give a dinuclear tellurium oxide [{(p-Me-C6H4)2TeBr}2(μ-O)] (4) with a bridging oxygen atom. Complexes 1–4 have been spectroscopically characterized and their crystal structures have been established by X-ray crystallography.

A new universal method was developed for the production of unsymmetrical and symmetrical diaryltellurium dichlorides and dibromides on the basis of the reaction of diaryl ditellurides with arenediazonium ions in the presence of copper(II) halides.
