were rapidly reduced with samarium diiodide by the addition of base in the presence of protic solvent at room temperature to the corresponding alcohols. Sodium benzoate was similarly reduced with samarium diiodide in the presence of H2O in a good yield. In the similar reactions of benzoic acid derivatives bearing carboxyl, formyl, carbamoyl, methoxyl, and chloro groups, these functional groups were
通过在室温下在质子溶剂的存在下将碱添加到相应的醇中,芳香族和脂肪族羧酸被二碘化钐迅速还原。在 H2O 存在下用二碘化钐同样还原苯甲酸钠,收率良好。在带有羧基、甲酰基、氨基甲酰基、甲氧基和氯基的苯甲酸衍生物的类似反应中,这些官能团也被还原为相应的醇或胺衍生物。有趣的是,苯甲酸的羧基和甲酰基部分被还原为甲基。
