芳基丙烯酰芳烃

When the proportion of the aryl halides was changed,the aromatic products with different number substitutes could be obtained.

通过研究我们发现，活泼酰基与烯丙基在偶联反应中活性相当，可得到不同成环方式的产物，且当改变卤代物比例时，将得到不同数量取代芳烃的产物。

It provides a route tothe compounds which contains three functional groups, two carbon-nitrogentriple bonds and one carbon-carbon double bond. In water, metallic indiumpromotes carbon-sulfur bond coupling reaction of aromatic sulfonyl chloride withsuitable organic halides to afford sulfones. In the last chapter, metallic tin mediated allylation of aldimines with allylbromide was revealed.

第三章，我们研究了在水相介质中金属铟促进的烯丙基溴对1，1-二氰基-2-芳基乙烯的Michael加成反应，生成一个含碳碳双键和二个碳氮叁键的三官能团化合物，另外，金属铟在水介质中还可以促进芳基磺酰氯与卤代烃发生碳硫键的偶联，生成砜。

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。
