Project summary:
The ambiphilic nature of donor groups containing heavier group 15 elements makes them attractive for the design of so-called Z-type donors. This term is based on the classification proposed by Green,1 who suggested distinguishing ligand types according to the nature of metal–ligand interaction. Thus, 2-electron donors are classified as L-type, 1-electron donors as X-type and 2-electron acceptors as Z-type ligands. The latter type corresponds to the bonding situation when transition metal behaves as a Lewis base toward a Lewis acidic ligand moiety. Recent interest in this peculiar class of ligands stems from the fact that the interaction between transition metal (M) and Z-type donor group (Z) may influence the electronic structure and reactivity of the resulting complexes. For instance, the extent of the M Z interaction enables modulating electron richness of the metal center and, hence, influencing its catalytic activity.2 This project aims at synthesis and investigation of ambiphilic ligands combining different pnictogen donor atoms linked through ferrocene backbone, their coordination chemistry and possible catalytic utilization.
