The reaction of polyoxyethylene diamines with polyoxyethylene diisothiocyanates leads to new crowns with thiocarbamide groups having 13- to 34-membered rings.Binuclear crown compounds with thiocarbamide groups are prepared by the reaction of polyoxyethylene diisothiocyanates with aza-15-crown-5

Macrocyclic thioureas of the and types, where R=CH2(CH2OCH2)nCH2 and (CH2)m (n=1, 2, 3, m=8), were obtained for the first time by the reaction of diamines with carbon bisulfide.The UV, IR, and PMR spectra of the compounds were studied.It was shown that they exist in the thione form in the crystalline state and in protic solvents.Thione - thiol isomerization is observed in nonpolar solvents.
