文摘
- •
Four catalytically relevant Pd(II) NHC complexes with bidentate N- and P-donor ligands were synthesized and characterized.
- •
The structures and conformations of the complexes were elucidated on the basis of combination of dynamic NMR and DFT studies.
- •
The results from dynamic NMR and DFT studies confirmed hindered rotation around C-N bond in studied imidazole complexes
- •
The fluxional behavior of P-donor ligands includes exchange between left-handed and right-handed phosphine propellers.
- •
Complexes 3 and 4 were evaluated as catalysts in Suzuki–Miyaura Reaction and exhibited excellent catalytic activity.
