    Industrially advantageous processes for producing a 2-alkyl-2-cyclopentenone in high yields starting from a 2-(1-hydroxyalkyl)cyclopentanone or a 2-alkylidenecyclopentanone, which are obtainable from a cyclopentanone and a carbonyl compound. A 2-(1-hydroxyalkyl)cyclopentanone represented by the following general formula (1): 1 (wherein R 1 , R 2 , R 3 , R 4 , R 5 , R 6 and R 7 each independently represents hydrogen atom, an alkyl group having 1 to 10 carbon atoms which may have one or more substituents or an aromatic group which may have one or more substituents, and each of (1) R 6 or R 7 with R 3 and (2) R 6 or R 7 with R 4 or R 5 may be together combined to form a ring which may have a double bond) is subjected to dehydrative isomerization in the presence of a bromine compound and/or an iodine compound.
