室温下SmI2-THF-HMPA-t-BuOH体系可顺利地将二硫代氨基甲酸酯还原断裂得到二硫醚和硫代甲酰胺; 同样条件下, 硫代氨基甲酸酯还原断裂得到二硫醚篅34The reductive cleavage of dithiocarbamic esters are promoted by the SmI2-HMPA-THF-t-BuOH System successfully to give disulfides and thiocarboxamides at room temperature in good yields; The reduction of thiocarbamic esters are also promoted by the same system to give disulfides and carboxamides.
