Abstract
A short and modular synthesis of symmetrically and nonsymmetrically substituted bisimidazolinylene N-heterocyclic carbene precursors is described. Two methods to establish dicopper(I) complexes of these compounds depending on the steric shielding of the carbene are reported.
Key words
alkylations - copper - carbene complexes - ligands - N-heterocyclic carbenes
