The reaction of (p-MeOC6H4)2TeO with two equivalents of HO3SCF3 and HO2PPh2 provided the tetraorganoditelluroxanes (F3CSO3)(p-MeOC6H4)2TeOTe(p-MeOC6H4)2(O3SCF3) (1) and (Ph2PO2)(p-MeOC6H4)2TeOTe(p-MeOC6H4)2(O2PPh2)·2 Ph2PO2H (2) in good yields. Compounds 1 and 2 were characterized by solution and solid-state 31P and 125Te NMR spectroscopy, IR spectroscopy, electrospray mass spectrometry, conductivity measurements and single crystal X-ray diffraction. In solution, compound 1 undergoes an electrolytic dissociation and reversibly reacts with traces of water to give the mononuclear cation [(p-MeOC6H4)2TeOH]+ and triflate anions. Theoretical aspects of the protonation and hydration of model telluroxanes R2TeO (R = H, Me, Ph) were investigated by preliminary DFT calculations and compared to the corresponding selenoxanes R2SeO. The tellurium dihydroxides R2Te(OH)2 seem to be more stable than the hydrogen-bonded complexes R2TeO·H2O.
