interesting, because it has two possible binding sites (phenolic OH group and fluorine atom) in the side arm. An X-ray crystal structure of the potassium thiocyanate complex of ligand 2 revealed that the oxygen atom of the phenolic OH group binds to the potassium cation incorporated in the crown ether ring, and two water molecules are enclosed by two armed crown ethers with the crown ethers forming partition
武装单氮杂15-冠-5具有4',6'-二氟-2'-羟基苄基作为附加的结合位点(组2)已被制备的曼尼希反应Ñ -methoxymethylmonoaza-15-冠-5与3- ,5-二氟苯酚。通过静电势计算(密度泛函计算,SVWN / DN *方法)预测3,5-二氟苯酚在曼尼希反应中的反应位点。配体2是有趣的,因为它在侧臂上有两个可能的结合位点(酚羟基和氟原子)。配体2的硫氰酸钾配合物的X射线晶体结构 据揭示,酚OH基团的氧原子与冠状醚环中结合的钾阳离子结合,并且两个水分子被两个武装的冠状醚包围,冠状醚形成分隔壁。
