We describe a simple and practical protocol for the synthesis of benzyl sulfones using readily available toluene derivatives and α-aminoacid sulfonamides. The reaction proceeds to afford a broad range of benzyl sulfones in moderate to high yields under silver catalysis. The mechanism possibly involves a Minisci-type formation of α-aminoalkyl radical, homolytic cleavage of a N-S bond to generate a
