    IUPAC recommended pK a values for this equilibrium in aqueous solution at 25 °C are 8.99 ± 0.04 (I = 0), 8.83 ± 0.02 (I = 0.1 M NaClO 4) and 9.00 ± 0.03 (I = 1.0 M NaClO 4; I = Ionic strength). [9] Values for mixed solvents are available. Very strong bases, such as organolithium compounds, will deprotonate acetylacetone twice.

    In 1,3-diketones, such as acetylacetone (2,4-pentanedione), the enol form is more favored. The acid-catalyzed conversion of an enol to the keto form proceeds by proton transfer from O to carbon. The process does not occur intramolecularly, but requires participation of solvent or other mediators.

    In this the carbon number 2 and 3 react with the amine groups, leaving the CO on number 5 alone. [12] Another condensation can happen with 2,5,6-triamino-4(3H)pyrimidinone giving 6-acetyl-2-amino-7-methyl-4(3H)pteridinone. [13] Grignard agents react.

    More common is the dimethyl derivative 2,4-Me 2 C 5 H 5. Additionally, many pentadienyl ligands are cyclic, being derived from the addition of hydride to η 6 -arene complexes or hydride abstraction from cyclohexadiene complexes.

    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] Total European and USA production was 15000 tonnes in 2000. [5] 2-Methyl-2,4-pentanediol exists as two enantiomers, (4R)-(−) and ...
