Abstracts
A series of adamantane functionalized diaza-lariat ethers 1–6 have been prepared and alkali
metal picrate extraction profiles determined. The ability of aza-crown ethers 1–6 to extract the alkali metal
picrates was compared with that of diaza-18-crown-6 (7) and N,N '-dibenzodiaza-18-crown-6 (8). Na+ and
K+ transport across bulk liquid membrane was also measured. The results of alkali metal cation extraction
experiments showed that lariat ethers 2 and 3, in which the adamantane molecule is linked to the diaza-18-
crown-6 by amine bond, have better complexation abilities for all cations compared to the parent crown
ethers 7 and 8, as well as a significantly higher selectivity for K+ than diaza-18-crown-6. However, diazalariat
ether 1 showed reduced, and 4–6 negligible extractability towards any of the alkali cations. Monte
Carlo conformational analysis pointed to the importance of conformational flexibility of the investigated
compounds for their extraction ability of alkali cations.(doi: 10.5562/cca2100)
