Process for producing 2-alkyl-2-cyclopentenones |
| abstract |
Industrially advantageous processes for producingna 2-alkyl-2-cyclopentenone in high yields starting from an2-(1-hydroxyalkyl)cyclopentanone or a 2-alkylidenecyclopentanone,nwhich are obtainable from ancyclopentanone and a carbonyl compound. A 2-(1-hydroxyalkyl)cyclopentanonenrepresented by the following general formula (1):n nis subjected to dehydrative isomerization or a 2-nalkylidenecyclopentanone represented by the following general formula (3):n nis isomerized. Both reactions take place in the presence of a brominencompound and/or an iodine compound. n In the above formulae, R 1 -R 7 nhave the meanings given in the description. |
