A process for preparing a dienynal compound of the following general formula (2):
CH2═CHC≡CCH═CH(CH2)nCHO (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):
CH2═CHC≡CCH═CH(CH2)nCH(OR1)(OR2) (1)
wherein R1 and R2 represent, independently of each other, a monovalent hydrocarbon group having 1 to 15 carbon atoms, preferably 1 to 8, more preferably 1 to 4, or R1 and R2 may be bonded to each other to form a divalent hydrocarbon group, R1-R2, having from 2 to 10 carbon atoms, and n represents an integer of 0 to 11, to obtain the dienynal compound (2).
一种制备以下通式(2)的二炔化合物的工艺:
CH2═CHC≡CCH═CH(CH2)nCHO (2)、
其中 n 代表 0 至 11 的整数,该工艺包括水解下式通式(1)的二烷氧基烷二烯化合物的步骤:
CH2═CHC≡CCH═CH(CH2)nCH(OR1)(OR2) (1)
其中 R1 和 R2 各自代表一个具有 1 至 15 个碳原子的单价烃基,优选 1 至 8 个,更优选 1 至 4 个,或者 R1 和 R2 可以相互键合形成一个具有 2 至 10 个碳原子的二价烃基 R1-R2,n 代表 0 至 11 的整数,从而得到二炔化合物 (2)。
