The objective is to cyclize and condense with different aromatic aldehydes to synthesize a series of aurones.

目的是与不同的芳香醛进行环合和缩合，以合成一系列的金酮。

The knoevenagel condensation of aromatic aldehydes with ethyl cyanoacetate proceeds smoothly in the presence of potassium fluoride giving products in high yield.

在氟化钾催化下， 芳香醛与氰乙酸乙酯发生克脑文格尔缩合反应，得到高产率的缩合产物。

Aldehydes possess anesthetic properties.

醛类具有麻醉的作用。

The aldehydes almost exist in everywhere and harm to people.

醛类化合物广泛存在于环境中，危害人体健康。

The formation mechanism of the aldehydes was also discussed.

同时探讨了这些醛类化合物的形成机理。
