Abstract

Diorganotellurides containing bulky aromatic substituents are found to catalyze the photooxidation of phosphite esters using aerobic oxygen as a terminal oxidant. A Hammett plot with substituted triaryl phosphites yielding ρ= 2.88 agrees with a nucleophilic oxygen transfer from telluroxide to phosphite.
