Baeyer-villiger
Hardchemistry
Baeyer–Villiger oxidation converts ketone to:
Select the correct option:
Solution
Incorrect! Answer:
Ester
- Reactants: A ketone is treated with a peroxy acid (e.g., mCPBA or CF3CO3H).
- Mechanism: The peroxy Oxygen attacks the carbonyl carbonyl, followed by the migration of one of the alkyl groups onto the Oxygen of the peroxide linkage.
- Functional Group Change: This 'insertion' of an Oxygen atom converts the ketone structure into an Ester structure (R−CO−R′→R−CO−OR′).
- Predictability: The more substituted alkyl group or the aryl group generally migrates preferentially (migratory aptitude: Tertiary > Secondary > Primary > Methyl).
