摘要：

Complex PdCl2(4,4'-bis-(n-C10F21CH2OCH2)-2,2'-bpy) (2b) was known to be a good recoverable catalyst under fluorous biphasic system. Complex 2b and PdCl2(4,4'-bis-(n-C11F23CH2OCH2)-2,2'-bpy) (2c), soluble in polar organic solvents at > 120 degrees C but insoluble at 25 degrees C, were demonstrated here as catalysts in the Pd-catalyzed Heck reaction under the thermomorphic mode and recovered for reusage, that is, the Heck reaction is homogeneously carried out at ca 140 degrees C, and after reaction the product mixtures remain in solution with the catalyst heterogeneously separated at room temperature.
