Synthetic and Structural Studies of (NHC)Pd(allyl)Cl Complexes (NHC = N-heterocyclic carbene)

摘要: The synthesis and structural characterization of a series palladium complexes bearing N-heterocyclic carbenes (NHC) as supporting ligands are described. reaction commercially available [Pd(allyl)Cl]2 isolated or in situ generated NHC leads to monomeric where one is bound the metal center, indicated by spectroscopic single-crystal X-ray diffraction studies. relative reactivity trend for these catalysts aryl amination discussed terms ligand steric properties, which vary function imidazole-nitrogen substituents perturbation resulting modulation ring planarity. concept buried volume used quantify demand each corresponding complexes.
