In addition, ioding was found to be an efficient catalyst for the imino Diels-Alder reaction of N-arylimine and enol ethers and the reaction provided tertrahydroqinolines in good yields. One pot synthesis of tetrahydroqinolines from aldehyde, aniline and enol ethers was also achieved using iodine as the catalyst. The chemical yield of the"one pot"reaction was comparable with that obtained using preformed N-arylimine.

此外我们也发现碘能够有效地催化N-芳基亚胺与烯醇醚的Diels-Alder反应，以很高的化学收率得到了四氢喹啉衍生物，并且发现碘也能够直接催化芳香醛、苯胺、烯醇醚的三组分&一锅&反应，获得的化学产率与使用预制的N-芳基亚胺相当。

Abstract— Three types of organic pollutants, phenol, phenylamine and dimethyl phthalate as the law of the wastewater treatment were researched with ECS.

文 摘 采用自制的电催化装置研究了苯酚、苯胺和邻苯二甲酸二甲酯三种有机污染物的废水处理规律。

Phenylenediamines, aminophenols, methoxyanil ines, and 1,4- hydroquinone, 1-naphthylamine were polymerized via the catalysis of horseradish peroxidase in mixed solvents of l,4-dioxane and water at amibient conditions by using hydrogen peroxide as the oxidant. Several factors influencing the polymer yield, such as the concentration of the substrate, pH value and oxidant amount were examined using a- phenylenediamine as substrate.
