strategy for the encapsulation of magneticnanobeads was developed by using the in situ self-assembly of an organic-inorganichybrid polymer. The hybrid polymer of [Cu(bpy)(BF(4))(2)(H(2)O)(2)](bpy)}(n) (bpy=4,4'-bipyridine) was constructed on the surface of amino-functionalized magnetic beads and the resulting hybrid-polymer-encapsulated beads were utilized as catalysts for the oxidation of silyl enolates
