Process for the preparation of 2-n-pentyl-3-(2-oxopropyl)-1-cyclopentanone

The valuable odoriferous material 2-n-pentyl-3-(2-oxopropyl)-1-cyclopentanone is prepared by a process which comprises hydrolysing and decarboxylating a compound of the formula STR1 wherein R represents a hydrocarbyl group, with water under pressure and in an initially substantially neutral medium. The use of 2-n-pentyl-3-(2-oxopropyl)-1-cyclopentanone as an odorant is also disclosed.
