Nature Communications: Successive Modification of Polydentate Complexes Gives Access to Planar Carbon- and Nitrogen-based Ligands(2019-04-03)

We demonstrate an efficient route to access related complexes with tetradentate CCCN and pentadentate CCCCN and NCCCN cores by successive modification of the coordinating atoms in complexes with a CCCC core. Combined experimental and computational studies reveal that the rich reactivity of metal-carbon bonds and the inherent aromaticity of the metallacyclic skeletons play key roles in these transformations.
