烯丙基苯基醚是一种有机化合物,化學式为C6H5OCH2CH=CH2。它在常溫常壓下是一种无色固体。

製備

烯丙基苯基醚是由苯酚钠烯丙基溴反应製備得來: [3]

當此反應在均匀乙二醇二甲醚溶液中进行时,产率几乎是固定的。然而,當反应在的乙醚浆液形式进行时,主要产物則是酸处理后的2-烯丙基苯酚

也有文献报道以苯酚为原料,碳酸钾为碱,在碘化钾的催化下和烯丙基氯丙酮中回流反应制得。[4]

反应

烯丙基苯基醚在酸催化剂存在下转化为2-烯丙基苯酚。这种转换是克莱森重排的一个例子。 [5] [6]

克莱森重排

氯化镍的催化下,使用硼氢化钠对其加氢,可以得到正丙基苯基醚。[7]它可以和三苯基硅烷((C6H5)3SiH)发生硅氢化反应,生成三苯基硅丙基苯基醚((C6H5)3Si(CH2)3OC6H5)。[8]

Serrated surface within a rock mass Macrostylolites in a limestone. Stylolites (Greek: stylos, pillar; lithos, stone) are serrated surfaces within a rock mass at which mineral material has been removed by pressure dissolution, in a deformation process that decreases the total volume of rock. Minerals which are insoluble in water, such as clays, pyrite and oxides, as well as insoluble organic matter,[1] remain within the stylolites and make them visible. Sometimes host rocks contain no...
