Comparative Metabolism of Certain Aromatic Acids. Ix. Fate of Some Halogen Derivatives of Benzoic Acid in the Aninal Body
In the literature one finds comparatively few references to the fate of the benaoic acid derivatives in the animal body, and even some rather conflicting statements regarding several of the corresponding hippuric acids. The object of our work, therefore, was to prepare the o-, m-, and p-chloro-, bromo-, and iodobenzoic acids, and, by feeding these substances to dogs and rabbits, to compare the ...
متن کاملN M R Spectra of Alkali and Halogen Nuclei in Alkali and Halogen Salts
NMR signals of 7Li, 23Na, 35C1, 39K , 79Br, 87Rb and 127I have been measured in various alkali and halogen salt powders relative to well defined aqueous solutions. W ith the known shielding constants of some of these solutions the nuclear magnetic shielding constants of the alkali and chlorine nuclei in crystalline powders were evaluated in the atomic reference scale. The theoretical values of ...
متن کاملI NQR Spectra of Iodobenzoic Acid and Iodophenol Derivatives. H-Bonds and C-I Characteristic Bonds of These Substances*
This is a review of investigations on iodo-benzoic acid, iodohippuric acid, and iodophenol derivatives by NQR, N M R , and emission Mössbauer spectroscopy. The influence of intermolecular, intramolecular, and bifurcated O H • I and O H • O bonds on the properties of iodine-carbon bonds is demonstrated. Ionized and non-ionized forms of tyrosine differ by the probability of H-bond formation. The ...
متن کاملHalogen NQR and Crystal Structure of Ammonium Halides
The 1 2 7 I-NQR of(HOCH 2 )3 CNH 3 I was determined in the range 77 < T/K<310. At T = 310 K the NQR signal fades out (Tm = 463 K). The 127I spectrum ( T =77 K.): v, =29.195 MHz, v2 = 14.597 MHz, rj(121l)=0, e Q # zz6 _ 1 (1 2 7 I) = 97.315 MHz, is in agreement with the crystal structure. The 127I NQR spectrum of l,3-diammonium-2,2-dimethylpropane diiodide, (H 3 NCH 2 C(CH 3 ) 2 CH 2 N H 3)2+ -2...
متن کاملInterplay Between Lithium Bonding and Halogen Bonding in F3CX•••YLi•••NCCN and F3CX•••NCCN•••LiY Complexes (X = Cl, Br; Y = CN, NC)
MP2 calculations with cc-pVTZ basis set were used to analyze intermolecular interactions in F3CX···YLi···NCCN and F3CX···NCCN···LiY triads (X = Cl, Br; Y = CN, NC) which are connected via halogen and lithium bonds. Those complexes with the role of LiY as halogen acceptor and lithium donor show cooperativity with energy values ranging between -1.97 and -2.92 kJ mol...
