Published in ELSEVIER SCIENCE BV in AMSTERDAM ,Authors: Motokura, K; Hashiguchi, K; Maeda, K; Nambo, M; Manaka, Y; Chun, WJ. The CAS is 94-41-7. Through research, I have a further understanding and discovery of Chalcone
Mesoporous silica-supported Rh complex catalysts were prepared by simple silane-coupling, followed by cornplexation, and characterized by FT-IR, SEM, Rh K-edge XAFS, and elemental analysis. Local structures of the Rh complexes in each sample were almost similar to those of a nonporous silica-supported diaminorhodiurn complex. Co-immobilization of a tertiary amine on the same silica surface induced slight changes to the Rh complex structure in the case of the support with smaller pores. The prepared catalysts showed high activity for the 1,4 addition reaction of phenylboronic acids. Co-immobilization of the tertiary amine increased the reaction rate by more than 7-fold, with turnover number of nearly 8500. The catalytic performance achieved with this novel system is with much higher than that reported previously with a nonporous silica-supported catalyst. The mesoporous silica-supported Rh complex-tertiary amine showed a wide substrate scope, including unsaturated ketones and nitriles. This co-immobilized tertiary amine may activate phenylboronic acid to enhance its reactivity in the transmetalation step with Rh-OH species.
