“…M–arene interactions of a neutral H-ATI ligand and related monoanionic (amino-)tropolonates with highly arenophilic [Ru(C 5 Me 5 )] + moieties have been reported . In order to evaluate the tendency of monoanionic ATI ligands to interact with other transition-metal centers via the π-electron cloud of the C 7 ligand backbone, reactions of 3-thf with precursors containing Rh + and W 0 as potentially arenophilic metal centers were investigated. , Reaction of 3-thf with [Rh(OTf)(cod)] did not give a cationic mixed metal species [NaRh(ATI Ph/ i Pr )(cod)][OTf], but salt elimination was observed to yield the rhodium compound [Rh(ATI Ph/ i Pr )(cod)] ( 5 ) as a yellow solid (Scheme ; OTf = triflate; cod = 1,5-cyclooctadiene). Alternatively, the more easily accessible rhodium precursor [RhCl(cod)] 2 can be used for the synthesis of 5 .…”

The coordination chemistry of alkalimetal aminotroponiminates (ATIs) was investigated based on (i) a lithium ATI, (ii) the first example of a sodium ATI, and (iii) the first example of a structurally characterized potassium ATI. In the lithium derivative of this series, the ATI ligand adopts a well-known κ 2 N binding mode. In contrast, the sodium and potassium ATIs show two different types of unprecedented polymeric structures in the solid state, unraveling a surprisingly rich coordination chemistry for the ATI ligand family. In the solid-state structure of the potassium compound, ATI ligands bridge the metal atoms in a μ 2 -κ 2 N binding mode. The sodium compound reveals a μ 2 -κ 2 Nκ 5 C coordination mode with an unusual interaction of a metal center with a C 7 ATI ligand backbone. NMR studies suggest that this type of interaction might also be accessible in solution. It was further studied by DFT calculations. The tendency of monoanionic ATI ligands to interact with transition-metal centers via their C 7 ligand backbone was investigated experimentally and theoretically using Rh + and W 0 as examples for potentially arenophilic metals.
