Abstract: ZnCl2-catalyzed selenolysis of epoxides with ArSeH was investigated in ethanol at room temperature. A variety of β-hydroxyl selenides were obtained in excellent yield and good regioselectivity by the simple, efficient and atomic economic procedure. Starting from epoxide o-cresyl glycidyl ether, a one-pot three-step procedure was used for the chemoselective synthesis of N-tosyl-1,3-oxazolidin-2-ones.

Key words: zinc chloride, arylselenol, epoxide, ring-opening reaction, regioselectivity, 1,3-oxazolidin-2-one
