Aliphatic amides as solvents and solubilizing agents

Aliphatic amides as solvents and solubilizing agents. Rohdewald, Peter; Moeldner, M. (Inst. Pharm. Chem., Westfael. Wilhelms-Univ., Muenster, Ger.). Dtsch. Apoth.-Ztg., 118(18), 653-7 (German) 1978. CODEN: DAZEA2. ISSN: 0011-9857. DOCUMENT TYPE: Journal CA Section: 63 (Pharmaceuticals) The soly. of aminophenazone (I) [58-15-1] in aq. HCONHR(R = H, Me, Et, CHMe2), HCONR2 (R = Me, Et), AcNR2(R = Me, Et, Pr), AcNHEt [625-50-3], EtCONHMe [1187-58-2], or AcCH2CONEt2 [2235-46-3] at 25° could not be correlated to the dielec. const. of aq. amide nor to vol. contraction or expansion phenomena. In highly dil. aq. amide the solubilizing effect is attributed to hydrophobic interaction of the amides with I, whereas in concd. aq. amide, amide-H2O solvates of I may be formed.

Proton NMR spectroscopic studies on acetoacetdiethylamide and its beryllium chelate

Proton NMR spectroscopic studies on acetoacetdiethylamide and its beryllium chelate. Sen, D. N.; Thankarajan, N. (Natl. Chem. Lab., Poona, India).There are some reagents with their cas registry numbers 2235-46-3 and 23849-25-4 are used in this study. J. Indian Chem. Soc., 53(8), 765-7 (English) 1976. CODEN: JICSAH. DOCUMENT TYPE: Journal CA Section: 73 (Spectra by Absorption, Emission, Reflection, or Magnetic Resonance, and Other Optical Properties) The enol-content of diethylacetoacetamide was detd. by the NMR spectroscopic method. The Be chelate of diethylacetoacetamide was prepd. and its NMR spectrum recorded for comparison with that of the ligand. Supporting evidences for K. H. Meyer's (1921) conclusions regarding keto-enols were obtained from a study of the solvent effect. .
