Outline of Final Research Achievements

Montmorillonite-supported cationic Si was found to be an active catalyst for allylsilylation of alkenes. The catalytic activity significantly enhanced by the addition of a small amount of water to the reaction mixture. The montmorillonite catalyst was also effective for the cyanation of alkenes using nitromethane as a CN source.
Bifunctional catalytic surface containing metal complex and organic amine was prepared by silane-coupling reaction. The Pd-complex-tertiary amine catalyst showed higher activity for the allylation of nucleophiles compared with only Pd complex-immobilized catalyst. Additionally, CuH-bisphosphine complex catalyst was prepared from hydrosilane, Cu salt, and bisphosphine ligand. The CuH complex exhibited excellent catalytic performances for reductive transformation of CO2.
