Abstract

p-Hydroxyphenyl tellurinic acid anhydride and 3-methyl-4-hydroxyphenyl tellurinic acid anhydride have been sythesized by alkaline hydrolysis of corresponding hydroxyaryl tellurium trichloride which in turn were obtained by the reactions of TeCl₄ with phenol and o-cresol, respectively. These arene tellurinic acid anhydrides have been investigated as oxidizing reagents in the conversion of benzoin to benzil, 4-methoxy and 4-nitrobenzylalcohol to corresponding benzaldehydes, thiophenol to diphenyl disulphide, triphenylphosphine to triphenylphosphine oxide and hydroquinone to p-benzoquinone. The oxidizing property was found to be more in case of 3-methyl-4-hydroxyphenyl tellurinic acid anhydride as compared to p-hydroxyphenyl tellurinic acid anhydride.
