Pd^{<scp>II</scp>} Complexes Possessing a Seven‐Membered N‐Heterocyclic Carbene Ligand

Abstract

Carbenes with a twist: A seven-membered N-heterocyclic carbene (NHC) ligand is prepared from an amidinium precursor, derived from 2,2′-dinitrobiphenyl, and yields the NHC–PdII complex [PdCl(allyl)(NHC)] (see scheme). This carbene framework exhibits a tortional twist that results in axial symmetry. This ligand class can be readily modified and is attractive for future application in asymmetric catalysis.
