Abstract

Anthranilic acid has been anchored to polystyrene, and rhodium, palladium, platinum and ruthenium complexes of this modified polystyrene have been prepared. These catalysts will reduce a variety of olefinic and aromatic hydrocarbons, and also nitrile, nitro and carbonyl functional groups, said carbonyl groups being present in either ketones or aldehydes.
