heterocycles with dialkynylphosphine oxides has been realized via cobalt/rhodium-catalyzed C–H bond activation. This protocol provides an efficient synthetic entry to functionalized 1,2-dihydrophosphete oxides in excellent yields via the merger of C–H bond activation and formal 1,2-migration of the phosphoryl group. Compared with traditional methods of synthesis of 1,2-dihydrophosphetes that predominantly
通过钴/铑催化的 C-H 键活化,实现了多种杂环与二炔基膦氧化物的高度立体和化学选择性分子间偶联。该方案通过结合 C-H 键激活和磷酰基的正式 1,2-迁移,以优异的产率提供了高效合成功能化 1,2-二氢磷酸盐氧化物的方法。与主要依靠化学计量金属试剂合成1,2-二氢磷酸酯的传统方法相比,该催化体系具有效率高、反应时间相对较短、原子经济性和操作简单等特点。还公开了所选1,2-二氢亚磷酸盐氧化物的光物理性质。
