A method for producing a compound (3),
by reacting a compound (1)
having R
1
and R
2
representing a hydrogen atom or a monovalent hydrocarbon group wherein a case where both R
1
and R
2
are a hydrogen atom is excluded,
with a compound (2)
having R
3
representing a divalent hydrocarbon group, R
4
and R
5
representing a monovalent hydrocarbon group, X representing a halogen atom, and m representing an integer of 0 to 2
the method comprising the steps of:
using 0.1 mol or more and less than 1 mol of a compound (4)
having R
6
representing a divalent hydrocarbon group and A representing a single bond or the like per 1 mol of the halogen atom in the compound (2), and
liquefying a mixture of hydrogen halide salts of the compounds (1) and (4) generated as a by-product to separate the mixture from the compound (3) and removing the mixture.
一种制备化合物(3)的方法,通过将具有R1和R2的化合物(1)与具有R3,R4和R5的化合物(2)反应而得到,其中R1和R2表示氢原子或一价碳氢基团,但不包括R1和R2都是氢原子的情况,X表示卤素原子,m表示0至2的整数。该方法包括以下步骤:使用0.1摩尔或更多但少于1摩尔的具有R6表示二价碳氢基团和A表示单键等的化合物(4)每1摩尔化合物(2)中的卤素原子,并将生成的化合物(1)和(4)的氢卤酸盐混合物液化,分离混合物以得到化合物(3),并去除混合物。
