Abstract
This invention relates to a process which comprises reacting one or more reactants in the presence of a metal-organopolyphosphorus ligand complex catalyst and optionally free organopolyphosphorus ligand to produce a reaction product fluid comprising one or more products, wherein said process is conducted at a carbon monoxide partial pressure such that reaction rate increases as carbon monoxide partial pressure decreases and reaction rate decreases as carbon monoxide partial pressure increases and which is sufficient to prevent and/or lessen deactivation of the metal-organopolyphosphorus ligand complex catalyst.
