Arene Tellurinic anhydride have recently been used as mild and selective oxidizing reagent. They are prepared y hydrolysis of organyl tellurium trichloride or oxidation of diorganyl tellurides. Prepared p-hydroxyphenyl tellurium(IV) trichloride, 3-Methyl-4-hydroxyphenyl-tellurium(IV) trichloride, p-hydroxyphenyl tellurinic acid anhydride (RTeO)2O as oxidizing reagent, 3-methyl-4-hydroxyphenyl tellurinic acid anhydride (RTeO)2O as oxidizing reagent. These hydroxyaryltellurium(IV) trichloride upon alkaline hydrolysis yield the corresponding tellurinic acid. Tellurinic acid upon dehydration give tellurinic acid anhydrides. The oxidizing property is more in case of 3-methyl-4-hydroxy phenyltellurinic acid anhydride as compared to p-hydroxyphenyl telurinic acid anhydride. As comparison of oxidizing property of these anhydrides with those of corresponding telluroxide, show these acid anhydride to be weaker oxidising agents than the respective telluroxide.
