  High-pressure functionalization of diaza-crown ethers: new synthesis of silver(1+) ion-specific binders

  摘要：

  High-pressure S(N)Ar reaction was first applied to the synthesis of a new crown ether family, which incorporated various heteroaromatics as potential cation binding sites in a unique fashion. In a CH2Cl2 liquid membrane transport experiment, several diaza-crown ethers having thiazole, oxazole, pyrazine, and pyridazine rings exhibited a perfect Ag+ ion selectivity. Cation extraction and C-13 NMR titration experiments revealed that attachment of a unique heterocycle to the diaza-crown ring, if in the proper position, significantly offered excellent Ag+ ion specificity. Since the binding and transport selectivities of these crown ethers were apparently higher than those with conventional crown ethers, the high-pressure technique provided a useful method for synthesis of a new specific crown ether family.
