N,N′‐Dialkyl‐, N,N,N′,N′‐Tetraalkyl‐ und N,N′‐Diaryl‐terephthalsäurediamide
Journal für Praktische Chemie, 1962AbstractAus Terephthaloylchlorid und prim. oder sek. aliphatischen Aminen werden in Äther bei Gegenwart von Triäthylamin N,N′‐Dialkyl‐ bzw. N,N,N′,N′‐Tetraalkyl‐terephthalsäurediamide dargestellt. Analog erhält man aus Arylaminen N,N′‐Diaryl‐terephthalsäurediamide. Von diesen Verbindungen wird die Stabilität bei höheren Temperaturen untersucht.

N,N?-dialkyl-N,N?-dinitrosulfodiamides
Bulletin of the Academy of Sciences of the USSR Division of Chemical Science, 1989N,N′-dinitrosulfodiamides are formed in the nitration of sulfodiamides with concentrated nitric acid or nitronium borofluoride, and also on substitutional nitration of the corresponding N,N′-di-tert.-butyl derivatives with those reagents. Sulfuryl chloride reacts with the disodium salt of ethylene N,N′-dinitramine to produce 2,5-dinitro-1,2,5 ...

Extraction of uranium(VI) with N,N,N′,N′-tetrabutylmalonamide and N,N,N′,N′-tetrahexylmalonamide
Journal of Radioanalytical and Nuclear Chemistry, 1998A new diamide N,N,N′,N′-tetrahexylmalonamide (THMA) was synthesized, characterized and used in the extraction of U(VI) from nitric acid solutions. N,N,N′,N′-tetrabutylmalonamide (TBMA) was also studied to test the steric hindrance. Factors affecting this extraction system, the concentration of the extractant, aqueous nitric acid and NaNO3 and the ...
