The present invention provides a process for preparing a terminal conjugated alkadienal compound of the following general formula (5):
CH2═CHCH═CH(CH2)aCHO (5)
wherein “a” represents an integer of 1 to 15, from a dialkoxyalkenyl alkoxymethyl ether compound of the following general formula (1):
R1CH2OCH2OCH2CH2CH═CH(CH2)aCH(OR2)(OR3) (1)
wherein R1 represents a hydrogen atom, an n-alkyl group having 1 to 9 carbon atoms, or a phenyl group, R2 and R3 represent, independently of each other, a monovalent hydrocarbon group having 1 to 15 carbon atoms, or R2 and R3 may form together a divalent hydrocarbon group, R2-R3, having 2 to 10 carbon atoms, and “a” is as defined above.
本发明提供了一种制备以下通式(5)的末端共轭烷二烯醛化合物的工艺:
CH2═CHCH═CH( )aCHO (5)
其中 "a "代表 1 至 15 的整数,由下式通式(1)的二烷氧基烯基烷氧基
甲醚化合物制备:
R1 O O CH═CH( )aCH(OR2)(OR3) (1)
其中 R1 代表氢原子、具有 1 至 9 个碳原子的正烷基或苯基,R2 和 R3 各自代表具有 1 至 15 个碳原子的一价烃基,或 R2 和 R3 可共同形成具有 2 至 10 个碳原子的二价烃基 R2-R3,"a "如上定义。
