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 sulfones under strictly stoichiometric amounts 30% H2O2 CH3CN solvent. This study represents first promising example successful employment calixarenes–polyoxometalate (POM) materials area catalytic oxidations.
