The dimethylamino (Me2N) group is arguably the most versatile functional group capable of highly efficient and site‐selective directed aromatic functionalizations at the ortho‐, meta‐, and para‐positions depending on reaction conditions. While the repertoire of Me2N‐directed reactions is growing at a rapid pace, the lack of a general method to transform this group to other functionalities hampers its
二甲基氨基(Me 2 N)基团可以说是最通用的官能团,能够根据反应条件在邻位,间位和对位进行高效和位点选择性的定向芳族官能化。尽管Me 2 N定向反应的库迅速增长,但缺乏通用的方法将该基团转变为其他官能团,妨碍了其在有机合成中的广泛应用。这里,我们报告镍-催化的Ç 芳基-和苄基二甲胺,其允许未充分利用的Me很大程度上是巨大的图书馆的转换N个borylations 2含N的有机分子成各种功能性分子通过利用现有的C财富的优点乙官能的方法。
