General description

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.

Application

The malonamide-based ionic liquid extractant was used in the extraction of europium(iii) and other trivalent rare-earth ions from nitric acid medium.

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

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

According to molecular dynamics simulations, uncomplexed malonamide ligands L and their neutral Eu(NO3)3L2 or charged EuL4(3+) complexes are surface active and adsorb at a water-"oil" interface, where "oil" is modeled by chloroform. Aqueous solvation at the interface is found to
