enol

1.Reaction of Dianion 8 with 4 To Form 7 and Enol 10.

反应形成酸根84710和烯醇.

2.Dihydrocodeinone enol acetate;

its salts 二可待因酮烯醇乙酸酯;

3.its salts 二可待因酮烯醇乙酸酯;

Dihydrocodeinone enol acetate;

4.Keto-enol tautomerizing of ethyl acetoacetate was studied by UV.It was conformed that the content of enol ethyl acetoacetate decreased with the increasing polarity of solvents.

本文以紫外光谱为手段研究乙酰乙酸乙酯的酮-烯醇式互变异构现象;所得结果证实其烯醇式含量随溶剂极性的增加而减少。

5.Keto-enol tautomerism is the most common tautomery phenomenon.Keto -enol themselves are the real chemical substance.

酮及烯醇互变是互变作通的现象,它们都是真实的化学实体。

6.In this thesis, the reaction of aldehydes with dimethyl -- dichlorosilane producingdimethylsilyl bis -- enol ethers has been studied.

本文对醛和二甲基二氯硅烷反应合成二甲硅基双烯醇醚进行了研究。
