CATALYTIC BEHAVIOR OF PQLYMER-BOUND PALLADIUM COMPLEXES FOR DECARBONYL-ARYLATION

The activities and stabilities of the polymer-bound palladium complexes fordecarbonyl-arylation were investigated in this paper.It was found that the activities ofpolymer-bound complexes are comparable to those of their homogeneous counterparts.Among the catalysts examined,the sulfur-containing polymer-bound palladium complexeshave high activity and better stability than the phosphine-,amine-and nitrile-containingpolymerie palladium catalysts.Experimental work was undertaken to evaluate the possibleside reactions.The factors which caused the catalyst deactivation were discussed and the in-flucnce of experimental parameters on the reaction was studied as well.
