| titleOfInvention | Process for preparing (9z,11e)-9,11-hexadecadienal |
| abstract | The present invention provides a process for preparing (9Z,11E)-9,11-hexadecadienal of the following formula (4), the process comprising: subjecting (2E)-2-heptenal of the following formula (1) to a Wittig reaction with a triarylphosphonium 9,9-dialkoxynonylide compound of the following general formula (2), wherein Ar represents an aryl group that may be same with or different from each other, and R1 and R2 represent, independently of each other, a monovalent hydrocarbon group having 1 to 15 carbon atoms, or R1 and R2 may form together a divalent hydrocarbon group, R1-R2, having 2 to 10 carbon atoms to form a (5E,7Z)-16,16-dialkoxy-5,7-hexadecadiene compound of the following general formula (3), wherein R1 and R2 are as defined above; and hydrolyzing the (5E,7Z)-16,16-dialkoxy-5,7-hexadecadiene compound (3) to form (9Z,11E)-9,11-hexadecadienal (4). |
