Abstract: A novel periodic mesoporous Au(I) organometalsilica as an active and reusable catalyst for alkyne hydration reaction was synthesized by co-condensation of phenyl silane and organometal bridged silane. Compared with the Au-PPh2-PMO(Ph)-G prepared by the grafting method, the Au-PPh2-PMO(Ph) catalyst showed high dispersion of Au(I) active sites, straightway mesopore channels, and the reduced diffusion limit. During the hydration of terminal alkynes, the Au-PPh2-PMO(Ph) catalyst not only exhibited higher catalytic efficiency than the un-immobilized Au(PPh3)Cl catalyst but also could be used repetitively, showing good potential in industrial application.
