Özet
Palladium-N-heterocyclic carbene complexes are widely investigated catalysts in cross-coupling reactions. However, studies about the catalytic activities of bridged bi-metallic complexes are quite rare. Therefore, in this study, anthracene-substituted one mono-metallic and one bridged bi-metallic PEPPSI-type Pd-NHC complexes were synthesized in order to compare their catalytic activities in Suzuki-Miyaura and Mizoroki-Heck reactions. Both complexes were fully characterized by H-1 and C-13 NMR, LC-MS, IR spectra and elemental analyses. The results of catalytic reactions clearly revealed that mono-metallic complex performs better catalytic activity than bi-metallic analogue in the use of same amount of palladium.
