Abstract

A number of pyrazole-derived dithioethers were prepared by the reaction of diisothiuronium salts and 2-(3,5-dimethylpyrazol-1-yl)ethanol tosylate in a basic aqueous solution. Diisothiuronium salts were prepared by the reaction of thiourea with alpha,omega-dibromoalkanes containing from two to nine methylene groups. The use of these salts allowed in situ generation ions dithiolate, thus eliminating the need to use hazardous dimercaptans. (c) 2015 Published by Elsevier B.V.
