An efficient method for the synthesis of tridentate PGeP– and PSnP–palladium complexes is developed. Structural analysis revealed that PSiP-ligand exerts the strongest trans influence and electron donation and that PGeP- and PSnP-ligands provide wider coordination sphere around the palladium. Preliminary studies demonstrated that both PGeP– and PSnP–palladium complexes work as an efficient catalyst for reductive aldol-type reaction, indicating promising utility in synthetic organic chemistry.
本研究开发了一种合成三叉PGeP-和PSnP-钯配合物的有效方法。结构分析表明,PSiP 配体具有最强的反式影响和电子捐赠作用,而 PGeP- 和 PSnP 配体在钯周围提供了更宽的配位圈。初步研究表明,PGeP- 和 PSnP-钯配合物均可作为还原醛醇反应的高效催化剂,在合成有机化学中具有广阔的应用前景。
