A metal-free sequential dual oxidative amination of C(sp3)–H bonds under ambient conditions was the first developed, affording imidazo[1,5-a]pyridines in good to excellent yields. The reaction was involved in two oxidative C–N couplings and one oxidative dehydrogenation process with six hydrogen atoms removed.
首次开发了在环境条件下无金属的C(sp 3)-H键的顺序双氧化胺化反应,可提供咪唑并[1,5- a ]吡啶,并具有良好或优异的收率。该反应涉及两个氧化C–N偶联和一个氧化脱氢过程,其中去除了六个氢原子。
