An easily accessible polyoxomolybdate鈥揷alix[4]arene hybrid 1 has been synthesized and applied as a heterogeneous catalyst in the sulfoxidation of thioethers to sulfoxides and to sulfones under strictly stoichiometric amounts of 30% H₂O₂ in CH₃CN as the solvent. This study represents the first promising example of successful employment of calixarenes鈥損olyoxometalate (POM) hybrid materials in the area of catalytic oxidations.
