摘要: β-环糊精(β-CD)是七个葡萄糖单元以α-1,4-糖苷键连成的锥形环状分子,此环中的空腔是疏水性的,因而象酶一样,可提供一个疏水的结合部位来和一些几何形状及大小合适的有机和无机分子形成包结络合物。

Abstract: The gas-solid bromination of biphenyl in the presence of β-cycled extrin has been studied.The experimental data indicated that the rate of consumption of biphenyl in the presence of β-cyclodextrin is ten times greater than that when no β-cyclodextrin is present.lt was found that this reaction has high para selectivity.
