Title: Metal-ligand complex catalyzed processes

Abstract: This invention relates to a process for separating one or more cyclic products from a reaction product fluid comprising one or more cyclic reactants, a metal-organophosphorus ligand complex catalyst, optionally free organophosphorus ligand, a non-polar solvent and said one or more cyclic products, wherein said process comprises: (1) reacting said one or more cyclic reactants in the presence of said metal-organophosphorus ligand complex catalyst, optionally free organophosphorus ligand and non-polar solvent to form a multiphase reaction product fluid; and (2) separating said multiphase reaction product fluid to obtain a non-polar phase comprising said one or more cyclic reactants, metal-organophosphorus ligand complex catalyst, optionally free organophosphorus ligand and non-polar solvent and a polar phase comprising said one or more cyclic products.
