Treating chloromethylated polystyrene with anthranilic acid and then various PdI2 complexes gave palladium complex catalysts. The colloidal palladium catalysts
containing rnetal particles of 2-13 nm in diameter
were prepared by the reduction of Pd2+-chelate resin complex with 1:1 methanol-water (pH = 12). The hydrcgenation activities of these catalysts were correlated with the polarity parameter
ET(25)
of the solvents used in the reaction. The hydrogen uptaken increased with decreasing the electron donor constant
En
of the ligand of Pd complex. The colloidal Pd catalyst
containing meral particles of 4-5nm in diameter
was active ca-talyst for the hydrogenation of alkenes.
