ketonizev.

/ˈkiːtənʌɪz/

Etymology: < keton- (in ketone n.) + -ize suffix.

Chemistry.

intransitive. Of a compound which undergoes keto-enol tautomerism: to change into the keto-form.

ΚΠ

1937 F. C. Whitmore Org. Chem. 345 The free enediol is unstable and ketonizes to the acyloin at once.

1938 L. F. Fieser in H. Gilman Org. Chem. I. ii. 55 The hydroxyl derivatives of benzene show much less tendency to ketonize than do the aliphatic enols.

1962 E. L. Eliel Stereochem. Carbon Compounds viii. 242 The enolate..ketonizes in such a way that the proton approaches equatorially.

Derivatives

ketoniˈzation n. the process of changing into a keto-form.

ΚΠ

1931 Canad. Jrnl. Res. 5 26 The suggested formation of the lignosulphonic acids by ketonization of a phenolic nucleus is most unlikely.

1937 F. C. Whitmore Org. Chem. 280 Ketonization gives acetic acid, esters, acid amides, acid chloride, etc.

1968 R. O. C. Norman Princ. Org. Synthesis i. 19 Compared with the ketonization of phenol.., the ketonization of β-naphthol is more favourable by about 11 kcal per mole.

1972 Jrnl. Chem. Soc.: Perkin Trans. 1 987/1 Kinetic control of enolisation and ketonisation is replaced by thermodynamic control at higher temperatures.
