Özet
A new series of methyl substituted imidazole-based N-heterocyclic carbene (NHC) palladium complexes (PdCl2(L-1)NHC(L-1 =pyridine) is reported. Structural definitions of Pd-PEPPSI complexes were determined by NMR spectroscopy, elemental analysis and LC-MS spectroscopy techniques. To evolve a more efficient catalytic system for electronically different aryl chloride substrates on the Suzuki cross-coupling reaction, complexes were used as pre-catalyst. Activity of palladium(II)-NHC complexes screened under mild reaction conditions in aqueous media. With this catalytic system, the reaction proceeded in moderate or good yields with low catalyst loading (0.1 mol%). [GRAPHICS] .
