A green protocol for the silylation of alcohols using bonded fluorous phase catalysis

The surface of a solid silica support has been functionalized with long perfluoroalkyl chains. The resulting surface layer readily adsorbs fluorous molecules from organic solutions. In this way, dirhodium() perfluorocarboxylate catalysts can be conveniently immobilized on a solid support. The result...

Zusammenfassung:The surface of a solid silica support has been functionalized with long perfluoroalkyl chains. The resulting surface layer readily adsorbs fluorous molecules from organic solutions. In this way, dirhodium() perfluorocarboxylate catalysts can be conveniently immobilized on a solid support. The resulting Bonded Fluorous Phase (BFP) catalysts display a high activity in the silane alcoholysis reaction using a solventless procedure and are easily recycled.
