ABSTRACT:
This invention relates to processes which comprise reacting one or more reactants in the presence of a metal-organopolyphosphite ligand complex catalyst and optionally free organopolyphosphite ligand, and an amount of a sterically hindered organophosphorus ligand different from the organopolyphosphite ligand of said metal-organopolyphosphite ligand complex catalyst, to produce one or more products. The sterically hindered organophosphorus ligands are useful as indicators of organopolyphosphite ligand depletion in said processes.
