Temperature‐Controlled Catalyst Recycling in Homogeneous Transition‐Metal Catalysis: Minimization of Catalyst Leaching

Reduce–reuse–recycle! One of the challenges in applied homogeneous catalysis is the efficient recycling of the valuable metal catalyst. The catalyst recycling concept of temperature-controlled multicomponent solvent systems was successfully applied to the hydroformylation of long-chain alkenes. The factors that signficantly influence catalyst leaching and how it can be minimized effectively were systematically investigated for the first time.
