We have developed a new, efficient method for the synthesis of benzylphosphonate and benzylphosphonothioate diesters via a palladium(0)-catalyzed cross-coupling reaction between benzyl halides and H-phosphonate or H-phosphonothioate diesters, using Pd2(dba)3(CHCl3) as a palladium source and Xantphos as a supporting ligand. Some mechanistic aspects of these reactions were investigated using 31P NMR
我们已经开发了一种新的,高效的合成方法 膦酸苄酯 和 苄基硫代磷酸酯二酯通过钯(0)催化的苄基卤和之间的交叉偶联反应H-膦酸酯 或者 硫代磷酸膦酯 二酯,使用 Pd 2(dba)3(CHCl 3)作为钯的来源,Xantphos作为支持的配体。使用31 P NMR光谱研究了这些反应的某些机理。
