series of monoor bis-sulfonylthioureas has been synthesized via nucleophilic substitution of potassium sulfonamides and sodium dithiocarbamate in water under mild conditions, and their properties as anionreceptors in the absence and presence of K + have been investigated by 1 H NMR spectroscopy. It was found that calix[4]crown-5 derivative 10 shows much higher selective complexation capability with
在温和条件下,通过磺酰胺钾和二硫代氨基甲酸钠在水中的亲核取代合成了一系列单或双磺酰硫脲,并通过 1 H NMR 光谱研究了它们在 K + 不存在和存在下作为阴离子受体的性质。发现calix[4]crown-5衍生物10在K+存在下与H2PO4的选择性络合能力比不存在K+时高得多,这表明K+和H2PO4的物理尺寸分别与主体化合物的相应空腔。
