Unusual main group element complexes with tridentate diketoamine ligands
- In this work, the ability of different diketoamines \(RN[CH_{2}C(tBu)=O]_{2}\) (R = H, benzyl) as suitable mono-, di-, or trianionic chelate ligands for the synthesis of new heavier carbene homologs is investigated. The simple diketoamine \(HN[CH_{2}C(tBu)=O]_{2}\) is capable to stabilize main group elements in low oxidation states by transferring two-electrons (\(\pi\)-donation) from its backbone. The ability to enable electron transfer is the most important feature of this ligand. This of course depends also on the redox properties of the element center (for example this ligand can stabilize Sn(+2) but not a Ge(+2) center). Notwithstanding its structural simplicity, this ligand displays a multi-faced chemistry. The bonding mode diversity stems from its ability to be oxidized and to tautomerize. Thus, several unexpected complexes were synthesized and characterized. Another ligand, the diketoamine \(RN[CH_{2}C(tBu)=O]_{2}\) (R = benzyl) has been used for the synthesis of other type of heavier carbene-homologs.
