In this dissertation, preparation of polysubstituted ethene and heterocyclic compounds based on 2-hydroxyalkyl phenyl selenides andα-phenylselenopropionic acid reagents were further investigated as follow: Firstly, O-ethyl-O-vinyl phosphonates were prepared in a one-pot, two-step transformation by Mitsunobu reaction of 2-hydroxyalkyl phenyl selenides with monoethyl esters of phosphonic acid in the presence of diethyl azodicarboxylate and triphenyl phosphine (PPh3) followed by oxidation-eliminatio...

中文摘要：本文主要进一步探索了2-羟基烷基苯基硒醚、α-苯硒基丙酸试剂在制备多取代乙烯和杂环化合物反应中的应用，具体研究内容和结果如下：一、在偶氮二羧酸乙酯和三苯膦(PPh3)存在下，苯基-2-羟基烷基硒醚和O-乙基膦酸单酯发生Mitsunobu反应，无需分离和纯化反应中间体，直接使用30 %的双氧水进行氧化-消除反应，提供了&两步、一锅&合成O-乙基-O-乙烯基膦酸酯的新方法，该方法反应条件温和，操作简便，产物收率良好(76-82 %)。

The degradation of 2, 4-dichiorophoxyacetic acid (2, 4-D) by ozonation combined with sonication (03/US) was investigated. Based on the authors' first paper about the synergistic effect of ozone and US, this paper presents intermediate products of 2, 4-D degradation. The main intermediates were 2, 4-dichiorophenol, benzopuinone, hydroquinone and organic acids, such as maleic acid and oxalic acid and soon.
