α‐Diazo esters are smoothly converted into the corresponding trifluoromethyl thio‐ or selenoethers by reaction with Me4NSCF3 or Me4NSeCF3, respectively, in the presence of catalytic amounts of copper thiocyanate. This straightforward method gives high yields under neutral conditions at room temperature and is applicable to a wide range of functionalized molecules, including diverse α‐amino acid derivatives
在催化量的硫氰酸铜存在下,通过分别与Me 4 NSCF 3或Me 4 NSeCF 3反应,α-重氮酯可顺利转化为相应的三氟甲基硫代或硒醚。这种简单的方法可在室温下在中性条件下提供高收率,适用于多种功能化分子,包括各种α-氨基酸衍生物。非常适合将三氟甲硫基或硒代基团晚期引入类药物分子中。
