An odorless, one-pot synthesis of nitroaryl thioethers via SNAr reactions through the in situ generation of S-alkylisothiouronium salts

Abstract

A newly developed C–S bond formation nucleophilic aromatic substitution (S_NAr) reaction in aqueous Triton X-100 (TX100) micelles has been disclosed. This chemistry, in which odorless, cheap and stable thiourea in place of thiols is used as the sulfur reagent, provides an efficient approach for the generation of nitroaryl thioethers, which are useful structural units of many bioactive molecules, rendering this methodology attractive to both synthetic and medicinal chemistry.
