产品说明 一般描述 2,3-二羟基萘是一种多羟基苯酚。它是在邻位具有羟基的芳族二羟基化合物。已经报道了其与钼(VI)配合物的反应。据报道，在 Cu(I)-双恶唑啉配合物催化下，2,3-二羟基萘不对称氧化偶联聚合可合成具有连续的 1,1-二-2-萘酚主链结构的聚(2,3-二羟基-1,4-萘)。已经研究了硝基邻苯二腈和 2，3-二羟基萘之间的硝基置换反应。 应用 2,3-二羟基萘可用于以下研究： - 通过在强酸存在下的脱水反应来合成二萘并[2,1-b;2′,3′-d]呋喃-6-醇。
- 用作用于纳米晶 TiO2 颗粒的表面改性的稠环邻苯二酚类配体。
- 作为通过阴极溶出伏安法研究海水中铁的化学形态中的吸附竞争配体。
- 用作环三磷腈衍生物合成中的非卤素阻燃剂
