Three-component cyclocondensation of primary aliphatic amines and amino derivatives of maleopimaric acid methyl ester with formaldehyde and carbochain (1,2-ethane-, 1,3-propane-, 1,4-butane-, 1,5-pentane-, 1,6-hexanedithiols) α,ω-dithiols or 3,6-dioxa-1,8-octanedithiol produced N -substituted thiazacycloalkanes.

Bis(1,5,3-dithiazepanes) have been synthesized via cyclocondensation of aliphatic α,ω-diamines and hydrazine with formaldehyde and ethane-1,2-dithiol. Palladium(II) sorption with bis(1,5,3-dithiazepanes) from nitric acid solutions has been studied via a static method. Bis(1,5,3-dithiazepanes) efficiently extract palladium(II) from 0.1−4 mol/L nitric acid solutions at room temperature.

A method of synthesis of N -carboxyalkyl-substituted dithiaza- and dioxadithiazacycloalkanes was developed consisting in a tricomponent [1+2+1]-cyclocondensation of amino acids with formaldehyde and aliphatic α,ω-dithiols (1,3-propane-, 1,4-butanedithiols, 3,6-dioxa-1,8-octanedithiol).

Изучены противоизносные и противозадирные свойства N-замещенных 1,3,5-дитиазинана и 1,5,3-дитиазепанов, полученных циклотиометилированием аминов (моноэтаноламин, пропиламин) с формальдегидом и SH-кислотами (H2S, 1,2-этандитиол), в минеральных маслах при введении их в количестве 3 мас. %.

Antiwear and extreme pressure properties of N-substituted 1,3,5-dithiazinane and 1,5,3-dithiazepanes obtained via the cyclothiomethylation of amines (monoethanolamine, propylamine) with formaldehyde and SH acids (H2S, 1,2-ethanedithiol), taken in an amount of 3 wt %, in mineral oils have been studied.

One-pot synthesis of bis-1,5,3-dithiazepanes by cyclothiomethylation of o-phenylenediamine, 4,4'-diaminodiphenyl, 4,4'-diaminodiphenyl oxide, and 4,4'-diaminodiphenylmethane with formaldehyde and 1,2- ethanedithiol was performed. Sorption properties of the newly synthesized bis[4-(1,5,3-dithiazepan-3-yl)-phenyl] oxide were investigated by the batch technique. High efficiency of the recovery of palladium(II) with this reagent from hydrochloric acid solutions at room temperature was shown.
