Following this, you tautomerise the nitroso compound to the oxime. The mechanism is exactly analogous to keto-enol tautomerism: Note that I've elected to draw the oxime with a (E)-configuration. Both (E) and (Z) oximes can form, but the (Z)-configured oxime cannot cyclise in the foll...
Tautomerism –In its unstable keto tautomer cyclohexanone, Phenol experiences keto-enol tautomerism, but as the keto form, only a tiny fraction of phenol remains. The equilibrium constant for enolization is roughly 10-13, indicating that at every moment there is only one in every ten trillion mo...
Next is the reversible change of an imine into an enamine, analogous to the reversible transformation of a ketone into an "enol," or alkene-alcohol. The conversion of the well-known ketone, acetone, well illustrates keto-enol tautomerism: CH3-C(=O)-CH3→ CH2=C(-OH)-CH3. The nitrogen ...
Tautomerism is an isomerism in which the isomers are readily interchangeable and are in dynamic equilibrium with each other. It is shown by the compounds which have an acidic α−hydrogen.Keto compoundsshow tautomerism. Recall the keto-enol tautomerism. ...

Is conversion of PABA to folic acid catabolic or anabolic? How can you best describe the molecule pyruvate? (a) It is a three carbon alpha-keto acid. (b) It is a molecule with a labile carbon dioxide. (c) It is a molecule that can undergo keto-enol tautomerism and get phosphorylated...
I simply had noted "The phosphite ester salt is subject to keto-enol tautomerism and if the enol isomer is predominant the Perkow adduct is formed otherwise the keto form results in the Michaelis-Arbuzov adduct." in Wikipedia. The examples they had were from hexachloroacetone and another beta-...
