sulfones with a facile combination of halides, sulfurdioxide surrogates and phosphate esters is described. When thiourea dioxide was employed as a reductive sulfurdioxide surrogate, alkyl–alkyl sulfones were obtained under transitionmetal free conditions. Aryl–alkyl sulfones were obtained with an extremely low catalytic loading (0.2 mol%) via altering the mask of sulfurdioxide surrogates to sodium
