Descrizione generale

4-Hydroxy-4-methyl-2-pentanone is commonly used as a solvent in various industries, including paints, coatings, adhesives, and printing inks.

Applicazioni

4-Hydroxy-4-methyl-2-pentanone can be used to synthesize:
  • Diolmonoesters by reacting with aldehydes via tandem aldol-transfer–Tischtschenko reaction catalyzed by trimethylaluminum.
  • Aldol-transfer products such as β-hydroxy ketones by reacting with various aldehydes in the presence of L-proline as a catalyst.
  • Mono-α-arylated ketones and esters via Pd catalyzed reaction with aryl halides and aryl triflates, respectively.

It can also be used as a complexing agent to synthesize double-metal cyanide (DMC) catalysts by reacting with metal salt (MX) and cyanometalate compounds.
