Preparation of Recyclable Pd(II) Organometal Catalyst with Bicontinuous Cubic Ia3d Mesostructure for Water-Medium Organic Reaction

Article Preview

Abstract:

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 (CH3CH2O)3SiPhSi(OCH2CH3)3. In water medium Sonogashira reaction, the as-prepared Pd(II)-PMO-KIT-6 exhibited higher catalytic activity than the corresponding Pd(II)-KIT-6 catalyst 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.
