Interaction of obtained N-oxyethylazacrown-ethers with cations of alkaline and alkaline-earth metals has been investigated. It has been shown that presence of oxyethyl groups in nitrogen atoms of diazacrown-ethers led to sharp increase of stability constants of complexes with ions Na+, K+ - of alkaline-earth metals. General method for the synthesis of N,N'-disubstituted diazacrown-ethers with terminal initial amino groups in side chain has been developed. Cryptands with thiocarbamide groups isolated from the main nitrogen atoms were obtained through the interaction of carbon bisulphide or polyoxyethylen diisothiocyonates with corresponding azacrown-ethers, containing aminogroups in side chain. .
