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

Treatment of arenetellurinic anhydride (1) with acetic acid or anhydride readily formed arenetellurinyl acetate (2).It underwent not only oxytellurinylation of an olefin but also intramolecular cyclofunctionalization of various hydroxyolefins to cyclic ethers.The latter reaction was effectively accelerated by addition of boron trifluoride etherate or tin(IV) chloride and highly regio- and stereoselective.The tellurium functional group introduced in the cyclic ethers could be manipulated into other versatile groups by telluroxide elimination, halogenolysis, and reductive detelluration.

New synthetic reactions utilizing arenetellurinic acid anhydrides are described.The anhydrides proved to be very useful reagents for the transformation of various functional groups.Furthermore they induced various intramolecular cyclofunctionalizations to yield many oxygen and nitrogen heterocycles.

Arenetellurinic anhydride reacts with hydroxyolefins in acetic acid at reflux to give cyclic ethers bearing a phenyltelluro group.A mechanism via intramolecular oxytellurinylation with arenetellurinyl acetate is proposed.
