A new and facile method for the preparation of arenetelurinic mixed anhydrides is described from diaryl ditellurides and phenyliodine (III) dicarboxylates. Hydrolysis of the arenetellurinic mixed anhydrides gives arenetellurinic anhydrides and a one-pot p

The reactions of acetylacetone (AcAc) with ArTeCl3 (I), Ar2TeCl2 (II) and Ar3TeCl (III) (where Ar = phenyl, 4-hydroxyphenyl, 4-methoxyphenyl, 4-ethoxyphenyl, 3-methyl-4-hydroxyphenyl and 3,4-dihydroxyphenyl) have been investigated.The I gives ArTe(C5H7O2)Cl2 (IV) type derivatives but II and III do not react even on prolonged refluxing in the presence of anhydrous AlCl3.The structural features of the new acetonylacetone derivatives (IV) have been explored by IR, PMR, and CMR spectroscopy.The effect of phenyl ring substituents on the keto-enol tautomerism of IVhas been found to be minor.The bond formation between Te and C1 of AcAc and intramolecular secondary interaction between the oxygen of AcAc and Te have been inferred from spectral data.

Several aryltellurinic acid anhydrides have been compared for their oxidising properties in acetic acid.Very high yields of quinones and disulphides can be obtained under conditions where phenols are not oxidised.
