dcterms:description
A series of supported catalysts has been prepared from palladium(II) acetate and mesoporous molecular sieves bearing various N-donor groups at their surface and probed in the Heck coupling between n-butyl acrylate and bromobenzene to give n-butyl cinnamate. The results indicate that the catalytic activity as well as the amount of leached metal depends on the nature of the nitrogen modifying group. The best catalysts were obtained from the sieves bearing the SiCH2CH2CH2NH2 or SiCH2CH2CH2NHCH2CH2NEt2 groups at the surface. When combined with sodium acetate, the former catalyst provided the coupling product with conversions as high as 84% under microwave irradiation for 30 min and 84% under solvothermal conditions (160 oC/4 h) whereas application of the latter catalyst resulted in conversions 90% and 71% under identical reaction conditions (all at 1 mol% Pd loading).
