SiliaBond Metal Scavenger are functionalized silica gels designed to react and bind metal complexes. The process for using scavengers is outlined in the scheme
To be effective, the Metal Scavengers need the ability and inherent functionality to remove metals in their various oxidation states from the reaction mixture. For example, upon completion of a palladium metal-catalyzed reaction, the metal residue contained in the reaction can exist in both Pd(0) and Pd(II).
Thiourea (Si-THU) is a versatile metal scavenger for all forms of palladium, and is widely used in the pharmaceutical industry.
Once complexed with a transition metal, it has also been reported as being an effective catalyst.
