We report herein a novel protocol to construct C–P bond from heteroaryl boronic acid with H-phosphonate diester under Pd–Ag catalyzed system without addition of base. This method, directly using commercial available heteroaryl boronic acid as the starting material, provides a new way to synthesize a variety of useful heteroaryl phosphonates.

钯催化杂芳基硼酸与H-膦酸酯二酯的CP偶联

我们在此报告了一种新的方案，可在Pd-Ag催化体系下，从杂芳基硼酸与H-膦酸酯二酯构建C-P键，而无需添加碱。该方法直接使用市售的杂芳基硼酸作为起始原料，提供了一种合成多种有用的杂芳基膦酸酯的新方法。
