A pyrene-connected tetra-imidazolium salt has been prepared starting from
commercially available 1,3,6,8-tetrabromopyrene, and used as tetra-NHC precursor in the
preparation of tetranuclear Rh(I) and Ir(I) complexes. The tetra-NHC ligand displays axial
chirality upon coordination to the MCl(cod) (M = Rh and Ir) fragments, giving rise to rightand left-handed helix conformations. The catalytic activity of the resulting complexes was
studied in two relevant reactions that lead to the formation of five- and six-membered oxygencontaining heterocycles, namely, the cyclization of acetylenic carboxylic acid and the coupling
of diphenylcyclopropenone with substituted phenylacetylenes. [-]
