| abstract |
A process for preparing a dienynal compound of the following general formula (2): CH 2 ═CHC≡CCH═CH(CH 2 ) n CHO (2), wherein n represents an integer of 0 to 11, the process comprising a step of hydrolyzing a dialkoxyalkadienyne compound of the following general formula (1): CH 2 ═CHC≡CCH═CH(CH 2 ) n CH(OR 1 )(OR 2 ) (1) wherein R 1 and R 2 represent, independently of each other, a monovalent hydrocarbon group having 1 to 15 carbon atoms, preferably 1 to 8, mere preferably 1 to 4, or R 1 and R 2 may be bonded to each other to form a divalent hydrocarbon group, R 1 -R 2 , having from 2 to 10 carbon atoms, and n represents an integer of 0 to 11, to obtain the dienynal compound (2). |
