Na-exchanged X type zeolite, commercially available as MS-13X, effectively catalyzes thiol-disulfane exchange reactions under aerobic mild conditions to give the unsymmetrical disulfanes in good-to-high yields. Various thiols and disulfanes are tolerant in the catalytic systems. Preliminary mechanistic studies suggest the involvement of base-catalyzed SN2-S displacement and/or addition-elimination mechanisms assisted by H-bonding interactions.
