Synthesis, Structure And Characterization Of Amide-Based Open-Chain Crown Ethers And Their Complexes

Fifteen new open-chain crown ethers of amide type have been synthesized on the basis of 1,2-dihydroxybenzene, 1,3-dihydroxybenze, 1,4-dihydroxybenze and 1,3,5-trihydroxybenze. Their structures are characterized by element analysis, IR and ~1H NMR. Their structure formulas are listed as follows:...
