Environmentally friendly synthesis of unsymmetrical dialkyl disulfides by reacting organic halides with thiourea and sodium thiosulfate in an aqueous medium
environmental awareness, the development of environmentally friendly reactions in aqueous media is the subject of an increasing number of studies. Hence, we report a novel three-component reaction of alkyl halides, thiourea and Bunte salts using non-toxic H2O as a benign reaction medium. After heating for 7 h, various unsymmetrical disulfides in high purity could be prepared in up to 92% yield. The substrates
