Efficient Synthesis of Lithium Selective Dihydroxy-14-Crown-4 Ether with Bulky and Rigid Subunits: Experimental and Theoretical Binding Studies |
| 초록 |
Intermolecular cyclization of bulky bis-epoxide with 1,2-dihydroxybenzene to synthesized lithium selective 14 membered crown ether having both rigid and bulky structures is reported. The rigid aromatic group provides rigidity of the 14-crown-4 ether backbone while the bulky subunit provides a blocking mechanism to prevent bigger metal ion to form a complex. The structures of the synthesized compounds were co nfirmed by 1H and 13C NMR. The binding constants the crown ether-metal ion complex was studied using 1H NMR titration experiments and Density Functional Theory calculation. This work was supported by the National Research Foundation of Korea (NRF) grant funded by the Ministry of Science, ICT & Future Planning (No. 2012R1A2A1A01009683) and the Ministry of Education (No. 2009-0093816). |
