Cyclic oligoketones composed of 3,3-dimethylpentane-2,4-diones showed crown ether-like alkali metal ion binding behavior with association constants up to 1.7 × 104 M−1 in chloroform/acetonitrile (v/v, 9/1). The binding properties have been used for catalysis in the Finkelstein reaction in a low-polarity solvent. Furthermore, novel ion-binding hosts were generated by terminal functionalization of linear
由 3,3-二甲基戊烷-2,4-二酮组成的环状低聚酮在氯仿/乙腈 (v/v, 9/1) 中表现出类似冠醚的碱金属离子结合行为,缔合常数高达 1.7 × 10 4 M -1 . 这种结合特性已被用于在低极性溶剂中进行 Finkelstein 反应的催化。此外,通过线性聚酮的末端功能化产生了新型离子结合主体。
