| Abstract: | Pd/Nb2O5 was prepared, characterized and tested in Suzuki-Miyaura cross-coupling reactions under ligand-free conditions. High yields and selectivities were observed within short reaction times and very low palladium loadings. |
| Keywords: | Heterogeneous palladium catalyst Solid-supported palladium Suzuki-Miyaura cross-coupling Ligand-free Microwave irradiation |
