葫芦脲是高度对称的刚性分子, 在试图改进Kim等氧化制取羟基葫芦脲的过程中发现, 葫芦[6]脲(CB[6]) 在多种过硫酸盐(过硫酸钾、过硫酸钠、过硫酸胺) 的氧化下, 除了可以获得羟基葫芦脲外, 还可以得到进一步分解产物草酸. 研究表明, CB[n] (n=5, 7, 8)及其羟基葫芦脲也存在类似的现象. 这是国内外首次发现葫芦脲在进行腰位C—H键羟基化的同时, 还可以进一步氧化形成草酸.

关键词: 葫芦脲, 羟基葫芦脲, 氧化, 草酸

Cucurbituril is a high symmetry and rigid structure. When cucurbit[6]uril (CB[6]) was oxidized with persulfate (e.g. potassium persulfate, sodium persulfate and ammonium persulfate), the main product was perhydroxy-cucurbituril and the minor one was oxalic acid. Oxalic acid was also obtained by the oxidization of both CB[n] (n=5, 7, 8) and perhydrox-cucurbituril with various persulfates. As far as we know, this is the first time to discover that both cucurbit[n]uril and perhydrox-cucurbit[n]uril can be destroyed to give a small molecule-oxalic acid.

Key words: cucurbituril, perhydroxy-cucurbituril, oxidation, oxalic acid
