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.

在水性介质中使用聚离子树脂氢氧化物从硫氰酸盐高效无金属合成有机二硫化物

描述了在水性介质中在聚离子树脂氢氧化物存在下由烷基和酰基甲基硫氰酸酯制备有机二硫化物的有效且无金属的方法。已使用两种不同的硫氰酸有机基酯制备了不对称的二硫化物，对该协议的进一步扩展进行了测试。
