The invention is directed to a process for preparing a 1,4-disubstituted cyclohexane compound of formula (I):
where A is —OH, —OR, Br, or Cl; and
R is a silyl group, a hydrocarbyl group, or an acyl group having 1 to 12 carbon atoms. The process includes the steps of reacting ethylene with a (2E,4E)-hexa-2,4-diene compound to produce a 3,6-disubstituted cyclohex-1-ene compound, and hydrogenating the 3,6-disubstituted cyclohex-1-ene compound to yield the 1,4-disubstituted cyclohexane compound of formula (I).
该发明涉及一种制备式(I)的1,4-二取代环己烷化合物的过程:
其中A为—OH、—OR、Br或Cl;
R为硅基团、烃基团或含有1至12个碳原子的酰基团。
该过程包括以下步骤:将乙烯与(2E,4E)-己二烯化合物反应,产生3,6-二取代环己-1-烯化合物,然后将3,6-二取代环己-1-烯化合物加氢处理,得到式(I)的1,4-二取代环己烷化合物。
