3-METHYL-2-PENTANONE Chemical Properties,Usage,Production
Chemical Properties
3-Methyl-2-pentanone is a colorless liquid with an odor reminiscent of peppermint.
Uses
3-Methyl-2-pentanone is used as a solvent and as an intermediate for syntheses of pharmaceuticals.
Synthesis Reference(s)
The Journal of Organic Chemistry, 41, p. 1939, 1976 DOI: 10.1021/jo00873a011
Tetrahedron Letters, 16, p. 4453, 1975 DOI: 10.1016/S0040-4039(00)91090-6
Synthesis
2-Butanone undergoes basecatalyzed aldolization with acetaldehyde to form
4-hydroxy-3-methylpentan-2-one. Acidcatalyzed dehydration to 3-methyl-3-penten-2-
one is followed by hydrogenation over a
palladium catalyst to give 3-methyl-2-pentanone.
