An efficient and metal-free method is described for the preparation of organic disulfides from alkyl and acyl methyl thiocyanates in the presence of poly-ionic resin hydroxide in aqueous medium. Further extension of this protocol has been tested using two different organyl thiocyanates to prepare unsymmetrical disulfides.
