A direct C–H/P–H functionalization of heteroaryl N-oxides with H-phosphonates under metal and oxidant free conditions was developed. Various heteroaryl phosphonate derivatives were obtained in up to 92% yield in a chemo- and regioselective manner.
通过无金属和氧化剂的条件,开发了一种直接的杂环氧化物N-氧化物与H-膦酸酯的C-H/P-H官能化反应。以高达92%的产率以化学选择性和位置选择性的方式获得了各种杂环膦酸酯衍生物。
