Allgemeine Beschreibung
The malonamide derivatives are obtained by the one-pot, five-component condensation reaction of isocyanide, Meldrum′s acid, arylidene malononitrile, and two amine molecules in CH2Cl2.
Anwendung
The malonamide-based ionic liquid extractant was used in the extraction of europium(iii) and other trivalent rare-earth ions from nitric acid medium.

Methyl tunnel frequencies, measured at 4 K, are found to be 455 +/- 8 kHz in methyl malonamide and 496 +/- 8 kHz in methyl ethyl ketone. The first is unaffected by deuteration of the amide groups. Measurements of the

The conformational and tautomeric compositions of malonamide, NH2-C(O)-CH2-C(O)-NH2 were determined by vibrational spectroscopy and theoretical calculations (HF/6-31G*, B3PW91/6-31G*). Solid state Fourier transform infrared and Raman spectra were analysed. They reveal the existence of a diketo tautomer. Theoretical calculations predict a

A general synthesis of 1,3-dicarbonylic compounds using multicomponent reactions of isocyanides is described. The process involves a Passerini three-component condensation of glyoxal derivatives, isocyanides and acetic acid, followed by metal mediated reductive or solvolytic removal of the acid component. Noteworthy

A new dipodal ligand, N,N'-bis{2-[(2-hydroxybenzylidine)amino]ethyl}malonamide (BHAEM) was synthesized by Schiff base condensation of N,N'-bis(2-aminoethyl)malonamide with two equivalent of salicylaldehyde and characterized on the basis of elemental analyses and various spectral (UV-vis, IR, (1)H NMR and (13)C NMR) data. The complexation

In this paper we used a surfactant-stabilized lyotropic lamellar model system to study the interfacial behavior of an ion-extracting agent: N(1),N(3) dimethyl-N(1),N(3)-dibutyl-2-tetradecylmalonamide (DMDBTDMA). An analysis of small-angle X-ray scattering (SAXS) and polarized attenuated total reflectance-Fourier transform infrared (ATR-FTIR) data enabled
