Outline of Final Research Achievements

Metal oxide-supported Au catalysts showed high activity for the C-O bond borylation of allyl esters. Detailed mechanistic study revealed that Au nanoparticles and the acid-base sites at their surroundings activated ally esters and boryl esters, respectively, thus enabling the reaction to proceed efficiently. On the other hand, SiO2-supported Au catalysts promoted the silylation of aromatic C-H bonds efficiently due to the generation of silyl cations from hydrosilanes by the cooperation of the weak basicity of the SiO2 surface and the soft Lewis acidity of Au nanoparticles. These investigations provided us a guideline for designing the catalysts that maximize the cooperative catalysis of supported Au nanoparticles and other catalytic components.
