Recently, along with public awareness of environmental issues there is growing need for the introduction of clean synthesis. The necessity for a better reagent for oxidation reactions in organic synthesis led us to introduce here bulky diaryl telluroxides which, due to the weak tellurium–oxygen bond, are expected to efficiently transfer the oxygen atom to organic substrates. Diaryl telluroxides, in particular 4,4′-dimethoxydiphenyl telluroxide 2c, are recognized as mild ...
