The compound is prepared by base-catalyzed condensation of 1-hydroxyhexane-2,5-dione, a derivative of hydroxymethylfurfural. [2] The structure has been confirmed by X-ray crystallography. [2] Quantum calculations also indicate that the enol is strongly favored relative to the diketo tautomer.
2-Pentanone or methyl propyl ketone (MPK) is a ketone and solvent of minor importance. It is comparable to methyl ethyl ketone , but has a lower solvency and is more expensive. [ 5 ] It occurs naturally in Nicotiana tabacum (Tobacco) [ 6 ] and blue cheese as a metabolic product of Penicillium mold growth.
As an enone, 2-cyclopentenone undergoes the typical reactions of α-β unsaturated ketones, including nucleophilic conjugate addition, the Baylis–Hillman reaction, and the Michael reaction. Cyclopentenone also functions as an excellent dienophile in the Diels–Alder reaction , reacting with a wide variety of dienes .
3-Methyl-3-penten-2-one is an unsaturated aliphatic ketone. It is an isomer of mesityl oxide and isomesityl oxide. It is a precursor of 3-methyl-2-pentanone (methyl sec-butyl ketone) and is obtained by acid-catalyzed dehydration of 4-hydroxy-3-methyl-2-pentanone. It is used as an intermediate in organic chemistry syntheses. [1]
Hydroxyacetone, also known as acetol, is the organic chemical with the formula CH 3 C(O)CH 2 OH. It consists of a primary alcohol substituent on acetone. It is an α-hydroxyketone, also called a ketol, and is the simplest hydroxy ketone structure. It is a colorless, distillable liquid.
2-Methyl-2,4-pentanediol (MPD) is an organic compound with the formula (CH 3) 2 C(OH)CH 2 CH(OH)CH 3. This colourless liquid is a chiral diol . It is produced industrially from diacetone alcohol by hydrogenation . [ 4 ]
