Here we report a silver-mediated trifluoromethoxylation of (hetero)aryldiazonium tetrafluoroborates by converting an aromatic amino group into an OCF3 group. This method, which can be considered to be a trifluoromethoxylation variation of the classic Sandmeyer-type reaction, uses readily available aryl and heteroaromatic amines as starting materials and AgOCF3 as trifluoromethoxylating reagents. The
在这里,我们报道了通过将芳香族氨基基团转换为OCF 3基团,银介导的(杂)芳基重氮四氟硼酸酯的三氟甲氧基化作用。该方法被认为是经典Sandmeyer型反应的三氟甲氧基化反应形式,它使用容易获得的芳基和杂芳族胺作为原料,并使用AgOCF 3作为三氟甲氧基化试剂。广泛的底物范围和简单,温和的反应条件使该转化成为构建芳基-OCF 3键的有价值的方法。
