simple, rapid, and nonhazardous deuteration of the C–C triple bond of α,β-acetylenic esters, amides, or acids by means of samarium diiodide in the presence of D2O, provides an efficient method for synthesizing 2,2,3,3-tetradeuterioesters, amides, or carboxylic acids, respectively. When H2O is used instead of D2O, saturated carboxylic esters, amides, or acids were isolated. A mechanism to explain these reduction
在D 2 O存在下,通过二碘化sa对α,β-炔烃酯,酰胺或酸的C–C三键进行简单,简单,快速且无危险的氘化,为合成2, 2,3,3-四氘代酸酯,酰胺或羧酸。当使用H 2 O代替D 2 O时,会分离出饱和的羧酸酯,酰胺或酸。已经提出了解释这些还原反应的机制。
