Process

A Formylation reaction in organic chemistry refers to organic reactions in which an organic Compound is functionalized with a Formyl group (-CH=O). The reaction is a route to Aldehydes (C-CH=O), Formamides (N-CH=O), and Formate esters (O-CH=O). A reagent that delivers the Formyl group is called a Formylating agent. A particularly important Formylation process is Hydroformylation which converts Alkenes to the homologated Aldehyde. The conversion of Benzene to Benzaldehyde is the basis of the Gattermann–Koch reaction.
