A library of novel C2-symmetric P,N ligands based on a Tröger’s base backbone was prepared via a concise two-stepsynthesis starting from a commercially available aniline derivative. X-ray crystallography and 31P NMR studies confirm that a single ligand molecule can accommodate two palladium atoms via coordination to nitrogen and phosphorus. Preliminary results proved the synthetic potential of this
通过简洁的两步合成法,从市售苯胺衍生物开始,制备了基于Tröger碱基主链的新型C 2对称P,N配体的库。X射线晶体学和31 P NMR研究证实,单个配体分子可通过与氮和磷配位而容纳两个钯原子。初步结果证明了该物种在芳基溴化物与芳基硼酸的Suzuki交叉偶联反应中的合成潜力。
