A procedure for the direct mechanochemical rhodium(III)-catalyzed C–H bond amidation of arenes with 1,4,2-dioxazol-5-ones as the nitrogen source has been developed. The transformation proceeds under solventless conditions and does not require additional heating. The corresponding ortho amidated products are formed in high yields and in shorter reaction times than in solution.
已经开发了一种直接机械化学铑(III)催化芳烃以1,4,2-二恶唑-5-酮为氮源酰胺化的方法。转化在无溶剂条件下进行,不需要额外的加热。与溶液相比,以高收率和更短的反应时间形成相应的邻酰胺化产物。
