A palladium-loaded ETS-10 molecular sieve has been used as a catalyst in Heck reaction. The catalyst exhibits high activity and selectivity towards the carbon–carbon coupling of aryl halides with olefins, even at low concentrations of Pd (0.009 to 1.4 mol% with respect to the substrate). In the case of the coupling of ethyl acrylate with iodobenzene, 96% conversion of iodobenzene with greater than 98% selectivity could be obtained within 1 h over a 0.2 wt % Pd-loaded catalyst. The catalyst activates aryl bromide and chloride substrates, and appears to be heterogeneous. The reaction has been investigated with different alkyl halides, olefins and bases. |
