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.
