Abstract / Full Text

Three-component condensation of urea with formaldehyde and propane-1,3-diamine in a molar ratio of 1 : 3 : 1 leads to the tricyclic 1,3,5,7,11,13,15,17-octaazatricyclo[15.3.1.17,11]docosane-4,14-dione. Condensation of urea with 1,3,7,9,13,15,19,21-octaazapentacyclo[19.3.1.13,7.19,13.115,19]octacosane (2 : 1) also leads to the formation of tricyclic product. As a result of the condensation of urea with formaldehyde and butane-1,4-diamine in the ratio of 2 : 4 : 1, 5,5′-butane-1,4-diylbis(1,3,5-triazinan-2-one) was obtained.
