A silver key to add CF3: In presence of in situ generated AgCF3, it is possible to trifluoromethylate aromatic triazenes in high ortho selectivity and good yields by means of a CH substitution (see scheme). Owing to the further transformation possibilities offered by triazenes, a variety of CF3‐substituted building blocks are then accessible.
一种
银键添加CF 3:在所生成的AgCF原位存在3,所以能够在trifluoromethylate高芳族
三氮烯邻位被C的装置的选择性和高产率 ħ取代(参见方案)。由于
三氮烯提供了进一步的转化可能性,因此可以使用各种CF 3取代的结构单元。
