However, fac-Alq3 has been obtained only in the subgram order by sublimation of mixed polymorphs of Alq3 or by thermal conversion of commercial Alq3 followed by acetone and chloroform treatment because synthetic control of a ligand configuration has been considered difficult as a result of the favorable formation of the thermodynamically stable mer isomer.

然而，因子Alq3得到了只有在subgram秩序的升华混合晶型的Alq3或热转换商业Alq3其次是丙酮，氯仿的待遇，因为合成控制配配置一直被认为困难是由于有利的形成的热力学稳定滨海异构体。

The synthesis of alkylcyclohexylbenzoic acid: take the synthesis of ethylcyclohexylbenzoic acid as a typical example. With the AlCl3 as the catalyst, cis+trans acetylcyclohexylbenzene is synthesized from the reaction of acetyl chloride, cyclohexene and benzene.

烷基环己基苯甲酸的合成研究：主要研究了乙基环己基苯甲酸的合成，以乙酰氯、环己烯、苯为原料，三氯化铝为催化剂，合成乙酰基环己基苯，用水合肼、氢氧化钾、一缩二乙二醇经过高温加热还原羰基(Wolff-黄鸣龙还原)，将所得到的乙基环己基苯用乙酰氯进行傅克酰基化得到乙基环己基苯乙酮，所得中间体经过处理之后直接得到反式产物，将反式异构体的乙酰基氧化得到反式烷基环己基苯甲酸。
