| Abstract: | Amide-functionalized N-heterocyclic carbene (NHC) precursors such as azolium compounds have been designed and synthesized. Reaction of PdCl2(CH3CN)2 with the NHC-Ag complex derived from the azolium salt gave (NHC)PdCl2]2 or (NHC)2PdCl2, whereas PdCl2(PPh3)2 reacted with the Ag complex to afford a mixed carbene/phosphine complex such as (NHC)(PPh3)PdCl2 together with a cationic (NHC)(PPh3)2PdCl]+Cl− whose structure was characterized by X-ray crystallographic studies. Thus, the library of NHC-Pd complexes with a tethered amide group has been successfully expanded. |
