synthetic pathways towards Pd-II complexes of functionalized bidentate diphenylphosphane ligands of the type [Pd(ligand)(anion)(2)] and [Pd(ligand)(2)](anion)(2) have been investigated. Eighteen different ligands have been used in combination with strongly (acetate, OAc-) or weakly (tosylate, OTs-) coordinating anions, The solid-state structure of some representative complexes was determined with X-ray crystallography
已经研究了 [Pd(ligand)(anion)(2)] 和 [Pd(ligand)(2)](anion)(2) 类型的功能化双齿二苯基膦配体的 Pd-II 配合物的合成途径。十八种不同的配体已与强(乙酸盐,OAc-)或弱(甲苯磺酸盐,OTs-)配位阴离子组合使用。一些代表性配合物的固态结构用 X 射线晶体学确定。表明固态结构完全保留在溶液中,通过H-1-和P-31-NMR光谱详细研究了[Pd(配体)-(阴离子)(2)]型配合物的形成. 根据配体结构,复合物通过多核中间体立即形成或根本不形成。
