| 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 R<sup>1</sup> and R<sup>2</sup> represent, independently of each other, a monovalent hydrocarbon group having 1 to 15 carbon atoms, or R<sup>1</sup> and R<sup>2</sup> may form together a divalent hydrocarbon group, R<sup>1</sup>-R<sup>2</sup>, 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 R<sup>1</sup> and R<sup>2</sup> 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). |
