AB  - Infrared spectroscopy studies of N-methyl benzamide and N-tert-butyl benzamide in 12 organic solvents were undretaken to investigate solvent-solute interactions. The wavenumbers of carbonyl stretching vibration nu(C=O) in different solvents were correlated with the solvent acceptor number (AN), the linear solvation energy relationships (LSER), Catalan solvent parameters (SA, SB and SPP) and Buckingham equation. For both studied amides significant correlation of the position of the carbonyl band with empirical parameters was obtained. Based on obtained results it was assumed that the amide self-association and the steric effects are most important factors that determine position of carbonyl groups band in the IR spectra.

AB  - Infinite dilution activity coefficients of pentane, hexane, heptane, cyclohexane, benzene, tetrachloromethane, dichloromethane, diethyl ether, tetrahydrofuran, acetone, ethyl acetate and methanol in N,N-diethyldodecanamide have been measured using gas-liquid chromatography. The measurements have been performed at 25, 35, 45 and 55°C. The solute partial molar excess enthalpies and entropies at infinite dilution have been calculated from the temperature dependence of the activity coefficients. Experimental values of activity coefficients at infinite dilution were compared with predictions based on the UNIFAC model.

AB  - As a part of a study on the structural characteristics of some new various N-alkyl-N-substituted 2-phenylacetamides the infrared and 1H N.M.R. spectra were obtained and interpreted. The synthesis of a various N-n-propyl-N-alkyl 2-phenylacetamides of the general formula PhCH2CON(nPr)R, wherein R is ethyl, isopropyl, n-butyl, t-butyl and cyclohexyl, were performed. The corresponding mixed secondary amines of the type HNnPrR were obtained by catalytic hydrogenation of the synthetized propylidenealkylamines. The 1H N.M.R. spectra of these unsymmetrically N,N-disubstituted amides have been studied and the peaks have been assigned in each cases to two possible conformational isomers, arising from the lack of free rotation about the C(O)N bond. These results are in accordance with our previous investigation of the structure of N-substituted 2-phenylacetamides.

AB  - In a continuation of our previous works the conformations of new N-(1,2,3,4-tetrahydro-1-napthyl and 1,2,3,4-tetrahydro-2-napthyl) substituted 2-phenylacetamides, PhCH2CONHR, were investigated by vibrational, 1H n.m.r. and mass spectra. N-monosubstituted 2-phenylacetamides were obtained by using the known Schotten-Baumann reaction of acylation of synthetized amides with phenylacetic chloride. On the basis of IR-data for diluted solutions(concentration below 10-3 mol. dm-3) of N-monosubstituted 2-phenylacetamides in carbontetrachloride the exact position of N-H stretching band were established. The informations concerning the fragmentation routes, the effect of overall and partial structures as well as the influence of the amide group substituents on the fragmentation pattern, were obtained by the study of the metastable ions. The investigation of the mass spectra of the deuterium labelled and the comparison with the corresponding unlabelled compound, gave the fragmentation pattern of the various conformers. From IR, NMR and mass data it can be concluded that our synthetized N-naphthyl substituted 2-phenylacetamides exist in cis and trans form.
