The oxygen of the enolate anion is protonated in the second step to create a neutral enol and regenerate the base. Web tautomeric equilibria are catalyzed by traces of acids or bases that are generally present in most chemical samples. Tautomers are rapidly interconverted constitutional isomers, usually distinguished by a different bonding location for a labile hydrogen atom and a differently located double bond. Web keto tautomer → enol tautomer in the first step, a base removes an α hydrogen to form an alkene by an e2 type process. Web keto enol tautomerization mechanism tautomerization under acidic conditions. To form an enol, an acid protonates a lone electron pair on the carbonyl. ( 5 votes) kavkazi29 12 years ago instead of water acting as a weak base and giving its electrons to the hydrogen forming the enol, can't water act as a nucleophile and attack the carbocation to form a diol. The mechanistic return to the keto tautomer begins with deprotonation of the hydroxyl hydrogen to produce an enolate ion. Web keto‑enol tautomerism was first introduced in section 9.4, in the discussion of the hydration of alkynes. Then lone pair electrons from the enolate anion attack an electrophilic h + through conjugation with the double bond.
The mechanistic return to the keto tautomer begins with deprotonation of the hydroxyl hydrogen to produce an enolate ion. Web keto enol tautomerization mechanism tautomerization under acidic conditions. Resonance requires that only electrons change positions. Step 1 in the first step, the base abstract the alpha hydrogen. Web keto enol tautomerization reaction and mechanism. To form an enol, an acid protonates a lone electron pair on the carbonyl. Web keto‑enol tautomerism was first introduced in section 9.4, in the discussion of the hydration of alkynes. Step 2 in this step, the oxygen of the enolate ion is protonated to form enol. ( 5 votes) kavkazi29 12 years ago instead of water acting as a weak base and giving its electrons to the hydrogen forming the enol, can't water act as a nucleophile and attack the carbocation to form a diol. Then, the acid’s conjugate base deprotonates the ɑ. You may wish to review these sections before proceeding.
