Identify the reactant and reagent: The reactant is a cyclobutanone, and the reagent is peracetic acid (CH3CO3H).
Recognize the type of reaction: This is a Baeyer-Villiger oxidation, where a ketone is converted into an ester by the insertion of an oxygen atom.
Determine the migratory aptitude: In Baeyer-Villiger oxidation, the group that migrates is typically the one with the highest migratory aptitude. The order of migratory aptitude is tertiary alkyl > secondary alkyl > primary alkyl > methyl.
Analyze the structure: The cyclobutanone has a methyl group and a methylene group adjacent to the carbonyl. The methylene group (secondary) has a higher migratory aptitude than the methyl group (primary).
Predict the major product: The methylene group will migrate, resulting in the formation of a lactone (cyclic ester) with a five-membered ring.
