In the presence of catalytic amount of cesium hydroxide, the nucleophilic addition reaction of selenols to alkyne sulfurnides occurred in tetrahydrofuran at room temperature under nitrogen atmosphere to give highly regio- and stereo-selective (Z)-1-arylthio-2-arylseleno alkenes in 70%~93% yields. The mechanism involved the formation of cesium arylselenides and the nucleophilic addition to the alkynyl sulfides in the presence of cesium hydroxide. The corresponding alkenes were obtained upon hydrolysis.

Key words: nucleophilic addition, regioselectivity, alkynyl thioether, cesium hydroxide, (Z)-1-arylthio-2-arylseleno alkenes
