A newly developed C–S bond formation nucleophilic aromaticsubstitution (SNAr) 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 nitroarylthioethers, which are useful structural units of many bioactive molecules, rendering
Using the transformation of allyl 2-nitrophenyl thioethers to 3,4-dihydro-2H-1,4-benzothiazines as an example the reductive cyclization of Ï-nitroalkenes to saturated N-heterocycles can be performed highly selective and with high yields if a combination of MoO2Cl2(dmf)2 as a catalyst and Ph3P as reducing agent are employed.
