Copper(II) 2,4-pentanedionate is used as a catalyst for carbene transfer reactions, coupling reactions and Michael addition reactions. It is also used as a catalyst for the polymerization of olefins and transesterification reactions as well as a PVC stabilizer. Further, it is used as a curing agent for epoxy resins, acrylic adhesives, silicone rubbers. In addition to this, it is used as a lubricant additive and paint drier.
