Green Chemistry on Solid Support

R. Bruce Merrifield's Peptide Synthesis in 1963 using cross linked polystyrene support opened an exciting area of research and since then many new reagent bound, substrate bound and catalyst bound methods have been developed. Present paper discusses some work on the polystyrene-divinylbenzene supported transition metal complex catalysts in general and Ruthenium-schiff base complex in particular and its application in different reactions viz. Hydrogenation of styrene to ethylbenzene and oxidation of benzyl alcohol to benzaldehyde. The polymer bound complex was found to be more effective than homogeneous counterpart. Untapped potential of such catalysts is also discussed.
