The oxidation of dithiaalkanes has been carried on in a gold(III) catalyzedphase-transferprocess. Using a higher concentration of catalyst and oxidant (procedure ) the bis(benzylthio)alkanes Bz-S-(CH2)-S-Bz (Bz = benzyl) were ·Oxidized to the corresponding monosulfoxide when n = 1 and to disulfoxide [bis(benzylsulfinyl)alkanes] when n = 2, 3, 4, 5, and 8. In more diluite conditions (procedure ) high
