  Orthogonal Reactivity of Acyl Azides in C–H Activation: Dichotomy between C–C and C–N Amidations Based on Catalyst Systems

  摘要：

  The dual reactivity of acyl azides was utilized successfully in C-H activation by the choice of catalyst systems: while selective C-C amidation was achieved under thermal Rh catalysis, a Ru catalyst was found to mediate direct C-N amidation also highly selectively. Investigations of the mechanistic dichotomy between two catalytic systems are also presented.

  A procedure for the [Cp*CoIII]‐catalyzed direct CH amidation of arenes with dioxazolone has been developed. This reaction proceeds under straightforward and mild conditions with a broad range of substrates, including anilides. A comparative study on the catalytic activity of Group 9 [Cp*MCl2}2] complexes revealed the unique efficiency of the cobalt catalyst.

  已经开发了用[Cp * Co III ]催化的芳烃与二恶唑酮直接CH酰胺化的方法。该反应在简单，温和的条件下与各种底物（包括酸酐）一起进行。对第9组[Cp * MCl 2 } 2 ]配合物的催化活性的比较研究表明，钴催化剂具有独特的效率。

  A [Cp*RhIII]‐catalyzed direct C−H amidation is carried out in ionic liquid. Both C(sp2)−H bonds of (hetero)arenes and alkenes and unactivated C(sp3)−H bonds can be easily amidated with high functional‐group tolerance and excellent yields under these conditions. Notably, using [Cp*RhIII]/[BMIM]BF4 (BMIM=1‐butyl‐3‐methylimidazolium) as the green and recyclable medium is environmentally benign, in light

  [Cp * Rh III ]催化的直接CHH酰胺化反应在离子液体中进行。在这些条件下，（杂）芳烃和烯烃的C（sp 2）-H键和未活化的C（sp 3）-H键都容易被酰胺化，具有很高的官能团耐受性和优异的收率。值得注意的是，考虑到诸如昂贵的铑催化剂的可重复使用性等特性，使用[Cp * Rh III ] / [BMIM] BF 4（BMIM = 1-丁基-3-甲基咪唑鎓）作为绿色且可回收的介质对环境无害。避免剧毒的有机溶剂，温和的反应条件以及较短的反应时间。
