This specification discloses an insoluble resin-metal compound complex, the method for its preparation, and its use in carrying out a catalyzed reaction. The complex is a weak base anion exchange resin which has been contacted with a solution of a coordination compound having at least two ligands connected to at least one central metal atom to bond chemically the resin to the metal atom by replacement of at least one of the ligands of the coordination compound by a functional group of the weak base anion exchange resin. The complex can be used as a catalyst for hydrogenation, carbon monoxide insertion, polymerization, isomerization, vinyl ester exchange, and ethylene oxidation reactions, among others.
A method of making an insoluble resin-metal coordinative complex compound comprising an insoluble weak base anion exchange resin having amine, phosphine, arsine, stibine, thiol or sulfide Lewis base substituents, coordinatively, nonionically bonded through said substituents to metal selected from the group consisting of platinum, palladium, rhodium, ruthenium, osmium, iridium, gold, cadmium, titanium, zirconium, hafnium, vanadium, chromium, molybdenum, tungsten, manganese, rhenium, iron, cobalt, nickel, copper, zinc, silver and mercury which comprises contacting said resin containing said substituents with a solution of a compound of said metal having at least two ligands coordinatively connected to said metal at a PH at which said substituents possess essentially no ion exchange properties and at a temperature below the decomposition temperature of said resin and said metal compound for a time sufficient for at least one of said ligands to be coordinatively exchanged for said Lewis base.
