Synthesis and characterization of amide-functionalized N-heterocyclic carbene–Pd complexes
摘要:
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)(2)PdCl2, 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)(2)PdCl]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. (C) 2011 Elsevier B.V. All rights reserved.
