| Popis: | A facile palladium(II)-porphyrin catalytic system has been developed for the Mizoroki-Heck coupling of aryl bromides with alkyl acrylates under mild conditions. Seven different porphyrins (H2TPP, H2TpCPP, H2TpAP, H2TpTP, H2TSTpSPP, H2TmHPP and H2TmCPP) and their complexes with palladium (Pd-TPP, Pd-TpCPP, Pd-TpAP, Pd-TpTP, Pd-TSTpSPP, Pd-TmHPP and Pd-TmCPP) were synthesized, and examined their catalytic role in the synthesis of alkyl cinnamates in DMF. The complex, Pd-TSTpSPP showed better activity in the present conversion. This finding has significant advantages like operational simplicity, easy synthesis of porphyrin ligands and their complexes with palladium, utilization of safer and recyclable catalyst and high yields of Mizoroki-Heck products. |
