Outline of Final Research Achievements

Both Pd-bisphosphine complex and DABCO were immobilized on a same SiO2 surface. The prepared catalyst was characterized by XAFS, XPS, and solid-state NMR measurements. The Tsuji-Trost reaction was examined using the prepared Pd catalyst. Product yield and selectivity significantly increased by DABCO on the same surface as an active site for nucleophiles. On the other hand, the enhancement effect was not observed in the case of homogeneous Pd-catalyzed reaction with DABCO.
Additionally, the SiO2-Al2O3 catalyst containing both In3+ cation and tertiary amine was prepared by ion-exchange and silane-coupling reaction. The prepared catalyst synergistically activates aldehyde and cyanide source by In cation and tertiary amine, respectively, affording an excellent yield of cyanoethoxycarbonylation product.
