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。

Axial group, substitution on the aromatic rings of SalenAlX, and co-catalyst all affect catalytic properties of these aluminum complexes.

席夫碱铝配合物轴向基团、苯环上的取代基团以及助催化剂等对其催化性能有很大影响。

In addition, the free group of negative ion came into being as a result of charge transfer between C=O band of vitamin M molecules and silver particles, and the C=O band was opened.

实验结果表明，VM在银表面的吸附发生在COO-基团，并且VM分子的C=O与银发生电荷转移后形成负离子自由基，碳氧双键打开，同时受VM分子吸附在银胶表面的影响，苯环结构发生了很大的扰动。

The key steps involve the utility of Evans oxazolidinone-mediated syn-aldol condensations to establish the C-9 configuration and the macrolides ring formation by intramolecular acylation.

此路线的关键步骤包括Evans模板控制的Aldol反应以及分子内苯环上的酰基化反应。

The structures were studied by IR and NMR. The absorption frequencies of the carbonyl group markedly depended on the coordination no. of the tin atom. The chem. shifts of 119Sn and 13C and the 1J(119Sn-13Sn) coupling constants of the compounds were determine Small structural changes around the tin atom were reflected in the 119Sn chem. shifts. For tributyltin arylcarboxylates, a relationship between 119Sn chem. shifts and Hammett constants of the para-substituents was found. The biol. activities of same compounds have been studied. They may be used as fungicides for fruit.

通过对它们的红外光谱、核磁共振谱(^1^3C， ^1^1^9Sn)的研究，表明羰基红外吸收频率与锡原子的配位数有密切关系，同样分子上的微小变化明显地表现在δ119Sn上，对位取代基苯甲酸酯的δ119Sn与苯环上取代基的Hammett常数之间存在良好的线性关系：δ119Sn=19.11σ+110.612 n=7，γ=0.9955着重研究了部分化合物在经济作物上的抗病原菌能力，结果表明，这是一类具有广谱性的有机锡化合物，抗菌活性优于对比药剂朴海因，接近或相当于多菌灵，它们同时具有较强的除草活性。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
