  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.

  Rhodium complexes with an indium metalloligand were successfully synthesized by utilizing a pyridine-tethered cyclopentadienyl ligand as a support for an In-Rh bond. The indium metalloligand dramatically changes the electronic and redox properties of the rhodium metal, thereby enabling catalysis of sp2 C-H bond activation.

  The Rh(III)-catalyzed amidation of C(sp2)-H bonds has been reported by employing the N-methoxyamide as a novel amino source. An excellent level of functional group tolerance can be achieved when N-methoxyamide derivatives are used as the amidating reagents. Importantly, several known bioactive compounds such as Aminalon, Pregabalin, Gabapentin, and Probenecid can be transformed to effective amidating

  通过使用N-甲氧基酰胺作为新型氨基源，已经报道了Rh（III）催化的C（sp2）-H键的酰胺化反应。当使用N-甲氧基酰胺衍生物作为酰胺化试剂时，可以达到极好的官能团耐受性。重要的是，可以将几种已知的生物活性化合物（例如阿米那隆，普瑞巴林，加巴喷丁和丙磺舒）转化为有效的酰胺化试剂，以利于开发新的生物活性分子。

The newly developed amidating reagent of 1,4,2-dioxazol-5-ones was applicable to a broad range of substrates with high functional group tolerance, releasing carbon dioxide as a single byproduct.

  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.

  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
