ABSTRACT:
This invention relates in part to processes for selectively producing one or more substituted or unsubstituted alkenals. The process hydroformylates at least one substituted or unsubstituted alkadienes, e.g., butadiene, or a mixture of one or more substituted or unsubstituted alkadienes in the presence of a hydroformylation catalyst, e.g., a metal-organophosphorus ligand complex catalyst, and at an alkadiene and/or carbon monoxide partial pressure sufficient to selectively produce at least one substituted or unsubstituted alkenals, e.g., pentenals. The substituted and unsubstituted alkenals produced by the processes of this invention can undergo further reaction(s) to afford desired derivatives thereof, e.g., hydrogenation to alkenols, particularly pentenols. This invention also relates to reaction mixtures containing one or more substituted or unsubstituted alkenals or alkenols as principal product(s) of those reactions.
