An easily accessible polyoxomolybdate–calix[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–polyoxometalate (POM) hybrid materials in the area of catalytic oxidations.
