| Outline of Final Research Achievements |
We investigated synthetic reactions of multinuclear Pd and Pt complexes having a planar core structure, and revealed their mechanism. Previously, we reported formation of the planar Pd4 and Pd3Pt1 complexes with bridging silylene ligands, but their selectivity largely depends on the reaction conditions. We conducted various kinds of the reactions, and found that the reaction starting from a dinuclear Pt-Pd complexes or Pd2 complexes as the starting materials produce the target complexes in the highest yield. Further studies on the reaction conditions revealed that it is composed of multistep processes composed of activation and formation of the Si-H bonds promoted by transition metal complexes and that relative stability of the starting material and target complex influences the product yield significantly. Based on the results, we obtained the best synthetic reactions of Pd4,Pd8, Pd3Pt1, Pt3 multinuclear complexes.
