摘要： 以对取代酚亚甲基桥三聚体和2,6-二溴甲基对取代酚为原料,在TiCl4催化下环化得到6种新的含不同取代基[Cl,Br,CH3,C(CH3)3]的杯[4]芳烃衍生物,核磁共振谱研究表明:它们在溶液中的优势构象为锥形构象。

Abstract: Six new calix[4]arenes containing different substituents[Cl, Br ,CH3,C(CH3)3] have been prepared from the cyclization of methylene bridged trimers of 4-substituted phenols and 2,6-bis (bromomethyl)-4-substituted phenols over the catalyst of TiCl4 in diglyme solvent with about 25% yield.NMR studies of new calix[4] arenes revealed that methylene protons signals appear at about δ3.40 and 4.20 as coupling two double peaks and methylene 13Csignals appear at about δ31.5.The preferred conformation of all six calix[4]arenes are cone conformation in solution.
