Carbonylation

As carbonylation is known in the chemical reaction for the introduction of a carbonyl group in organic chemical compounds.

These include, among others:

• Formylation
• Hydrocarboxylation

• Koch reaction: alkenes react with carbon monoxide and water, nickel tetracarbonyl - catalysis at about 250 ° C and 20 MPa to, saturated monocarboxylic acids,
• The carbonylation of arenas - in the simplest case of benzene - takes place under the conditions of the Friedel -Crafts acylation. From the arenas and phosgene arise as carboxylic acid chlorides, which cause significant hydrolysis to carboxylic acids.
