Английская Википедия:Cyclopentanone
Cyclopentanone is the organic compound with the formula (CH2)4CO. This cyclic ketone is a colorless volatile liquid.
Preparation
Upon treatment with barium hydroxide at elevated temperatures, adipic acid undergoes ketonization to give cyclopentanone:[1]
- (CH2)4(CO2H)2 → (CH2)4CO + H2O + CO2
Uses
Cyclopentanone is common precursor to fragrances, especially those related to jasmine and jasmone. Examples include 2-pentyl- and 2-heptylcyclopentanone.[2] It is a versatile synthetic intermediate, being a precursor to cyclopentobarbital.[3]
Cyclopentanone is also used to make cyclopentamine, the pesticide pencycuron, and pentethylcyclanone.[3]
It is also used as a precursor to cubane-1,4-dicarboxylate, which is used to synthesize other substituted cubanes, such as the high explosives heptanitrocubane and octonitrocubane.[4]
