allenylphosphonates and related compounds based on a palladium(0)‐catalyzed reaction of propargylic derivatives with H‐phosphonate, H‐phosphonothioate, H‐phosphonoselenoate, and H‐phosphinate esters. The reaction is stereoselective and stereospecific, and provides a convenient entry to a vast array of allenylphosphonates and their analogues with diverse substitution patterns in the allenic moiety and at the phosphorus
我们开发了一种新的合成烯丙基膦酸酯和相关化合物的方法,该方法基于钯(0)催化的炔丙基衍生物与H-膦酸酯,H-膦酰硫代酸酯,H-膦酰基油酸酯和H-膦酸酯的反应。该反应是立体选择性的和立体特异性的,并且提供了进入大量烯丙基膦酸酯及其类似物的便利入口,所述烯丙基膦酸酯及其类似物在所述烯丙基部分和在磷中心具有不同的取代模式。还研究了这种新反应的一些机理方面。
