THE EFFECT OF MODIFICATION OF COORDINATING GROUPS ON THE CATALYTIC BEHAVIORS OF POLYMER CATALYSTS
摘要:
Several polymer-supported palladium complex catalysts containing two different coordinating groups were prepared and the cooperative effect of the coordinating groups on the catalytic behaviors of polymer catalysts was studied. It was found that poly(acrylic acid-co-acrylonitrile)-Pd complex(PAA-AN-Pd) is a more active and stable catalyst for hydrogenation than both poly(acrylic acid)-Pd and poly(acrylonitrile)-Pd complexes. A marked change of catalytic behaviors of poly(N-substituted maleamic acid-co-styrene)-Pd complexes was observed in comparison with poly(maleic acid-co-styrene)-Pd complex.Acetophenone was reduced to 1-phenyl ethanol by poly(N-phenyl maleamic acid-co-styrene)-Pd complex (N-1-Pd),but ethylbenzene was obtained using poly(maleic acid-co-styrene)-Pd complex as a catalyst.The influence of solvents,additives and N/Pd gram atomic ratio on the catalttic behaviors of the polymer complexes was investigated.
