An alternative concept for the recycling of homogeneous catalysts has been developed, which combines the aspects of the two‐phase technique with the principles of thermo‐regulated phase‐transfer catalysis. Special temperature‐dependent multicomponent solvent systems make it possible to carry out a single‐phase reaction by repression of the miscibility gap at reaction temperature and guarantee an easy catalyst/product separation by the two‐phase technique at room temperature.
