  2. Cyclopentanecarboxylic acid - Wikipedia

    en.wikipedia.org/wiki/Cyclopentanecarboxylic_acid

    It is a colorless nonvolatile oil. It can be produced by the palladium-catalyzed hydrocarboxylation of cyclopentene: [2] C 5 H 8 + CO + H 2 O → C 5 H 9 CO 2 H. An alternative route involves base-induced ring contraction of 2-chlorocyclohexanone to give the ester methyl cyclopentanecarboxylate, which can be hydrolyzed to the carboxylic acid. [3]

    The alkyl (R') group is named first. The R−C(=O)O part is then named as a separate word based on the carboxylic acid name, with the ending changed from "-oic acid" to "-oate" or "-carboxylate" For example, CH 3 CH 2 CH 2 CH 2 COOCH 3 is methyl pentanoate, and (CH 3) 2 CHCH 2 CH 2 COOCH 2 CH 3 is ethyl 4-methylpentanoate.
