Herein, we report the redox-neutral, intermol., and highly branch-selective amidation of allylic C-H bonds enabled by Cp*IrIII catalysis. A variety of readily available carboxylic acids were converted into the corresponding dioxazolones and efficiently coupled with terminal and internal olefins in high yields and selectivities. Mechanistic investigations support the formation of a nucleophilic IrIII-allyl intermediate rather than the direct insertion of an Ir-nitrenoid species into the allylic C-H bond. In the experiment, the researchers used many compounds, for example, Di(1H-imidazol-1-yl)methanone(cas: 530-62-1SDS of cas: 530-62-1)
Di(1H-imidazol-1-yl)methanone(cas: 530-62-1) is a coupling agent in the synthesis of dipolar polyamides for nonlinear optical applications and polypeptides. It also used to make β-keto sulfones and sulfoxides, lead sequestering agents, and β-enamino acid derivatives.SDS of cas: 530-62-1
