Claims
- 1. A heterogeneous catalyst consisting essentially of anthranilic acid complexed with a metal selected from the group consisting of rhodium, ruthenium, palladium and platinum, said anthranilic acid complex being chemically linked through the amino group thereof to a polymeric support having reactive sites thereon for effecting a chemical linkage between the anthranilic acid complex and said polymer.
- 2. The catalyst of claim 1, wherein the metal complexed with anthranilic acid is rhodium.
- 3. The catalyst of claim 1, wherein the metal complexed with anthranilic acid is palladium.
- 4. The catalyst of claim 1, wherein the polymeric support is chloromethylated polystyrene.
- 5. A process for the preparation of the catalyst of claim 1 which comprises reacting anthranilic acid in an inert organic solvent with a polymer substrate having reactive sites thereon for effecting a chemical linkage between the amino group of said anthranilic acid and said polymer substrate, and thereafter contacting the thus treated polymer substrate, in an inert organic solvent, with a compound of a metal selected from the group consisting of rhodium, ruthenium, palladium and platinum for a time sufficient to effect a complexation reaction therebetween.
- 6. The process of claim 5, wherein said compound is a rhodium compound.
- 7. The process of claim 6, wherein the complex of rhodium with anthranilic acid which is chemically linked to said polymer substrate is thereafter treated with a reducing agent effective to reduce said rhodium to a lower valent state.
- 8. The process of claim 5, wherein said compound is a palladium compound.
- 9. The catalyst of claim 1, wherein the reactive sites on said polymeric support are CH.sub.2 Cl groups.
