Hydroformylation - an overview | ScienceDirect Topics

Hydroformylation (Equation (14)) is one of the very largest homogeneous catalytic reactions carried out by industry making over 15 billion pounds of aldehyde products each year.These are subsequently hydrogenated to alcohols or oxidized to carboxylic acids. There are several recent excellent reviews on hydroformylation catalysis (cf. Refs: 7, 7a–7c).
