Synergic Deprotonation Generates Alkali‐Metal Salts of Tethered Fluorenide‐NHC Ligands Co‐Complexed to Alkali‐Metal Amides

Synergic combinations of alkali‐metal hydrocarbyl/amide reagents were used to synthesise saturated N‐heterocyclic carbene (NHC) ligands tethered to a fluorenide anion through deprotonation of a spirocyclic precursor, whereas conventional bases were not successful. The Li(2) derivatives displayed a b...

description Synergic combinations of alkali‐metal hydrocarbyl/amide reagents were used to synthesise saturated N‐heterocyclic carbene (NHC) ligands tethered to a fluorenide anion through deprotonation of a spirocyclic precursor, whereas conventional bases were not successful. The Li(2) derivatives displayed a bridging amide between two Li atoms within the fluorenide‐NHC pocket, whereas the Na(2) and K(2) analogues displayed extended solid‐state structures with the fluorenide‐NHC ligand chelating one alkali metal centre.
