P⌒O环钯配合物的合成及对Suzuki交叉偶联反应的催化性能
摘要:
对水溶性的二苯基膦丙酸钠(PROPANa)的合成方法进行了改进,将Michael加成和皂化反应一步完成,简化了操作,收率为87%。研究了它的Pd(Ⅱ)配合物催化对溴甲苯与对氟苯硼酸的交叉偶联反应,结果表明,该类配合物室温下,水/有机两相体系中催化对溴甲苯与对氟苯硼酸的交叉偶联反应,产率达97%,具有很高的催化活性。

Synthesis of P⌒O Coordinated Cyclopalladated Complex and Its Catalytic Activity for Suzuki Cross-Coupling Reaction
Abstract:
Water-soluble Phosphine Ligand PROPANa was synthesized by an improved method,in which Michael addition and the saponification reaction were completed in one-step with a yield of 87%.Its P⌒O coordinated cyclopalladated complex exhibits a high catalytic activity for Suzuki cross-coupling reaction between 4-bromotoluene and 4-fluorophenylboronic acid in a mixture of aqueous and organic solvents at room temperature.
