The electroreduction or chemical reduction with zinc powder has been found to be effective to intramolecular coupling of aromatic diimines yielding 1,4-diazacrown ethers. The latter reduction was particularly effective to formation of 1,4-diaza-12-crown-4

Sewenteen new macrocyclic lactonolactams were obtained by the acylation of N,N'-dimethylpolyoxyalkanediamines with acid dichlorides in benzene under conditions of high dilution.The coefficients of cationic selectivity in the series of alkali and alkaline-earth metals were determined for them, and compounds which exhibit high calcium selectivity were found.
