Preparation
Upon treatment with barium hydroxide at elevated temperatures, adipic acid undergoes ketonization to give cyclopentanone:
(CH2)4(CO2H)2 → (CH2)4CO + H2O + CO2Uses

Cyclopentanone is common precursor to fragrances, especially those related to jasmine and jasmone. Examples include 2-pentyl- and 2-heptylcyclopentanone. It is a versatile synthetic intermediate, being a precursor to cyclopentobarbital.
Cyclopentanone is also used to make cyclopentamine, the pesticide pencycuron, and pentethylcyclanone.
