【 摘 要 】

A heterogenous Pd(Ⅱ) organometal catalyst with bicontinuous cubic Ia3d mesostructure was synthesized by surfactant-directed co-condensation of Pd［PPh₂(CH₂)₂Si(OCH₂CH₃)₃］₂Cl₂ and (CH3CH₂O)₃SiPhSi(OCH₂CH₃)₃.In water-medium Sonogashira reaction,the as-prepared Pd(Ⅱ)-PMO-KIT-6 exhibited higher catalytic activity than reference catalyst Pd(Ⅱ)-KIT-6 and could be used repetitively for more than 4 times,which could reduce the cost and even diminish the environmental pollution from heavy metallic ions,showing a good potential in industrial applications.
