Abstract: N-methylolchloroacetamide, N,N'-oxymethylenebischloroacetamide and N,N'-methylene bischloroacetamide were synthesized, which has got different reactive capability and were reacted with alkaline salts of alkyl xanthogenic acids. Optimal conditions for the synthesis of N, N'-oxydimethylene- and N, N'-methylenebisalkylxanthogenatoacetamides, whose structure has been studied by IR and NMR spectroscopy methods and are uniquely consistent with the formulas attributed to them. The structure of all synthesized compounds was proved by studying their physicochemical properties, including the determination of refractive indices (n20D), specific gravity (d 204) and the calculation on their basis of molecular refraction. With their subsequent comparison, elemental composition and IR spectroscopy. The IR-spectrums of absorption were taken with the SPECORD-75IR IR spectrophotometer, made by Karl-Zeis (GDR) firm, using prisms KBr in the 4000-400 cm-1 region. Absorption bands (most characteristic): stretching vibrations of the C-H bond 2928-2856 cm-1, stretching vibrations of the N-H 3384-3192 cm1 bond, stretching vibrations of the C = O 1648 cm-1 carbonyl group, and an intense absorption band of 768 and 556 cm-1 C-Cl bonds correspond to functional bonds and groups of synthesized compounds, which confirms their structure. The structure of the compounds was also confirmed by 1H NMR and 13C NMR spectra, taken in a solution of dimethyl sulfoxide (DMSO d6). NMR spectra were recorded on “Bruker AC300” spectrometer with operating frequency of 300.13 MHz and 75.47 MHz.
Key words: xanthogenic acids, chloroacetamide, condensation, N- chloroacetamide, N,N'-methylene bischloroacetamide.
