Outline of Final Research Achievements |
Hydrosilylation of aromatic aldehyde was achieved by using triplatinum complex, with bridging Si-ligands, [Pt3(SiAr2)3(PMe3)3] as the catalyst. Spectroscopic measurement of the reaction mixture suggested that the catalyst apparently kept the multinuclear structure because of self-healing nature of the complex under the reaction conditions. Kinetic measurement of the catalysis and comparison of the results with those obtained from monoplatinum complex-catalyzed hydrosilylaion revealed that the reaction in this study proceeded via new and unique pathways. The Si-ligands of the triplatinum complex were converted into a hydrogenated form, and reacted with the substrate by taking advantage of the mutlinuclear structure. The catayst was regenerated by the favorable coordination of the ligands, which completed structure recovery of the catalyst.
