What process converts aldehyde to alkene?
Hydroformylation, also known as oxo synthesis or oxo process, is an industrial process for the production of aldehydes from alkenes. This chemical reaction entails the net addition of a formyl group (CHO) and a hydrogen atom to a carbon-carbon double bond.
How do you convert alkenes to aldehydes?
Alkenes in which the carbon(s) of the double bond possess one or more hydrogen atoms react with ozone (O 3) to generate aldehydes. The reaction of propene with ozone to form acetaldehyde and formaldehyde illustrates this method of preparation.
