用Sm/CdCl_2/THF-H_2O(4/1)体系在原位获得活性金属镉,继而使二硒醚与卤代烃在室温下反应得到不对称单硒醚,该反应条件温和,中性,产率良好,提供了合成不对称单硒醚的一条新途径。
The active metal cadmium was obtained in situ with Sm / CdCl 2 / THF-H 2 O (4/1) system, then the diselenide and halogenated hydrocarbon were reacted at room temperature to obtain asymmetric monosaprenyl ether. The reaction conditions were mild, The good yields provide a new way to synthesize asymmetric monosulfonates.
