摘要：
A method for synthesizing 9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide or its derivatives has a step of introducing 6-chloro-6H-dibenz[c,e][1,2]oxaphosphorin or its derivative, an acid compound and water into a reacting chamber to form an organic layer having 9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide or its derivative and an aqueous layer. Because the acid compound is from an external source and has a catalyzing effect, employing the method can prevent side reaction from occurring and increase yield of 9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide or its derivative. Furthermore, the method is a one-pot operation of hydrolysis, dehydration and cyclization, so the method does not require purification of intermediates. Therefore, the method is time-and cost-saving and requires less organic solvent, resulting in less pollution to the environment.
摘要（中）：
合成9,10-二氢-9-氧杂-10-磷杂菲-10-氧化物或其衍生物的方法具有引入6-氯-6H-二苯并[c，e] [1,2]氧杂磷杂环丁烷或其衍生物的步骤 ，酸化合物和水加入到反应室中以形成具有9,10-二氢-9-氧杂-10-磷杂菲-10-氧化物或其衍生物和水层的有机层。 由于酸化合物来自外源并具有催化作用，所以采用该方法可以防止发生副反应，提高9,10-二氢-9-氧杂-10-磷杂菲-10-氧化物或其衍生物的产率。 此外，该方法是水解，脱水和环化的一锅操作，因此该方法不需要中间体的纯化。 因此，该方法节省时间并且需要更少的有机溶剂，导致对环境的污染较少。
