| Outline of Final Research Achievements |
Structure regulation of metal clusters is an important issue because the functionality of the metal clusters depends on the shape and number of the metal ions. In this study, I focused on carbon, a fundamental elements in organic chemistry as templates, and I gathered coinage metals onto one carbon atom or an aromatic ring.
Firstly, I constructed a carbon-centered, dicationic cluster having six coinage metals supported by phosphine ligand via metal exchange. Also, I found the cluster can be formed with N-heterocyclic carbene ligands.
Next, a synthetic method to construct phosphine-supported 1,2-Au(I) substituted benzenes via metal exchange from a corresponding boron compound was developed. Substituents on the phosphorus atom were crucial for the construction of the 1,2-digoldbenzenes. this method would be able to apply to construction of fully metal-subsutituted aromatic compounds. Accumulation of coinage metal complexes on to the digold benzenes was also studied.
