A novel, simple and eco-friendly method to synthesize thioamides from aryl nitriles and sodium sulfide (Na2S·9H2O) catalyzed by 1,8-diazabicyclo[5,4,0]undec-7-enium acetate ([DBUH][OAc]) ionicliquid (IL) at roomtemperature was developed in this paper. In this reaction, readily available inorganic salt (Na2S·9H2O) serves as the sulfur source, and various functional groups of aryl nitriles were well

Propargyl thioimidates synthesized from readily-available starting materials are cyclized into non-aromatic dihydrothiazoles with high chemoselectivity using copper (I) iodide as a catalyst. These molecules engage in ene-type reactions with aldehyde, imine, and azo reacting partners with concomitant aromatization. A one-pot tandem hydroamination/ene process has been developed.
