efficiently converted into the corresponding trifluoromethylthio‐ or selenoethers by reaction with Me4NSCF3 or Me4NSeCF3, respectively, in the presence of catalytic amounts of copper thiocyanate. These Sandmeyer‐type reactions proceed within one hour at room temperature, are applicable to a wide range of functionalized molecules, and can optionally be combined with the diazotizations into one‐pot protocols
在催化量的硫氰酸铜存在下,分别与Me 4 NSCF 3或Me 4 NSeCF 3反应,可以将芳族和杂芳族重氮盐有效地转化为相应的三氟甲硫基或硒醚。这些Sandmeyer型反应在室温下在一小时内即可进行,适用于多种功能化分子,并可选择性地与重氮化反应合并为一锅法操作。
