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.
