文摘

12-Tungestocobaltic acid, H5CoW12O40, was immobilized on nanosilica from rice husk ash to produce H5CoW12O40@nanosilica as a bifunctional nanocatalyst. The TEM result showed that the particles are mostly spherical in shape, and that they have an average size of approximately 10?nm. The catalytic activity of this catalyst was investigated in Mannich reaction of various aldehydes, ketones, and amines in water. This rapid procedure afforded structurally diverse β-amino ketones in high to excellent yields. Short reaction time, simple work-up procedure, elimination of toxic solvents, and low catalyst loading are the advantages of this procedure.
