Ohtaki, Hitoshi published the artcileIonic equilibriums in mixed solvents. VI. Dissociation constants of aliphatic diamines in water-methanol solutions, HPLC of Formula: 10517-44-9, the publication is Journal of Physical Chemistry (1971), 75(1), 90-2, database is CAplus.

Dissociation constant of protonated 1,2-diaminoethane, 1,3-diaminopropane, and 1,4-diaminobutane have been determined potentiometrically at 25¡ã in various H2O-MeOH mixtures containing 0.1M NaCl as an ionic medium. Ion products, Kw(S), in the mixtures have been calculated and used for calculations of pK’s of the acids, equilibrium of hydronium ions with alkoxonium ions being taken into consideration. Since values of pK2 – pK1 of the diamines have been independent of solvent compositions, interactions between charged sites in a mol. may scarcely be affected with the variation of the solvent composition

Mori, Sadao published the artcileThin-layer chromatography of diamines, dicarboxylic acids, and ¦Ø-amino acids, Name: Propane-1,3-diamine dihydrochloride, the publication is Journal of Chromatography (1970), 47(2), 224-31, database is CAplus.

A method, which involves thin-layer chromatog. and densitometry, was developed for the quant. and qual. determination of the diamine dihydrochlorides, dicarboxylic acids, and ¦Ø-amino acid hydrochlorides recovered from acid hydrolyzed copolyamides prepared from diamine-diacid and (or) ¦Ø-amino acids (or their lactams). Two different solvent systems consisting of PhOH-BuOH-HCO2H-H2O and PhOH-HCO2H-H2O were used. The qual. anal. of the 3 homologous series was attained on the same chromatogram. For quant. determination the method has an average relative error of ¡À5%. A linear relation between the R’m values [R’m = log (1/1.1 Rf -1 )] and the solute C numbers was observed. The deviation from linearity for the longer chain compounds might be caused by a gradient effect. The linearity between Rf values and the number of C atoms depended upon the exptl. conditions.

We have successfully synthesized 3,4,5-substituted 1,4-dihydropyridines (1,4-DHPs) from amine hydrochloride salts, aldehydes, and acetals in good yields without the addition of a catalyst. The synthesized 1,4-DHPs exhibit various wavelengths of fluorescence, which could be tuned by changing the substituents at the 3- and 5-positions of the 1,4-DHPs.

Hojo, Yasuji published the artcileSpecific ability of sulfur-ligands to remove mercury-203-labeled organomercury from hemoglobin in comparison with nitrogen-ligands, SDS of cas: 10517-44-9, the publication is Radioisotopes (1975), 24(10), 684-8, database is CAplus.

Organomercurials (chloromerodrin [62-37-3], methylmercuric chloride [115-09-3], ethylmercuric chloride [107-27-7] and phenylmercuric acetate [62-38-4]) bound to sulfhydryl groups of Hb were removed by chelating agents including sulfur-ligands (penicillamine [52-67-5], glutathione [70-18-8]) and nitrogen-ligands (EDTA [60-00-4], glycine [56-40-6], polyethylenediamines). The effect of sulfur-ligands was higher and more sp. than that of nitrogen-ligands. A linear correlation was observed between the extent of organomercurial removal and the stability constant (log K1) of the organomercury complex with sulfur- and nitrogen-ligands. At a fixed value of log K1, sulfur-ligands were more effective than nitrogen-ligands. With the exception of chloromeredin, a linear correlation was also observed between the average percentage of removal and the Taft’s polar substituent constant for the organic moiety of the metal. The average removal percentage by sulfur-ligands increased in the order: ethylmercury > methylmercury > phenylmercury, whereas that by nitrogen-ligands was similar.

Diamines [NH₂(CH₂)_xNH₂] (x = ¡Ü10) decreased betacyanin efflux from beetroot disks, especially at x = 7. Triamines [NH₂(CH₂)_xNH(CH₂)₃NH₂] (x ¡Ü 8) had a similar effect, but increased total ion loss (x = 4-10). Tetraamines [NH₂(CH₂)₃NH(CH₂)_xNH(CH₂)₃NH₂] (x = 2-4) also reduced betacyanin efflux. Spermine potentiated the toxic effects of guazatine and dodine in beetroot disks, but with Ca reduced the induced ion efflux in swede disks, spinach leaves, and apple cells; putrescine, cadaverine, and spermidine did not have such an effect. Monoguanidines [NH₂C(=NH)NH(CH₂)_x-1Me], esp x = 10-12 and diguanidines [NH₂C(=NH)NH(CH₂)_xNHC(=NH)NH₂), especially x = 12, caused efflux of betacyanin and ions.

Fiuza, S. M. published the artcileOn the correction of calculated vibrational frequencies for the effects of the counterions – ¦Á,¦Ø-diamine dihydrochlorides, Recommanded Product: Propane-1,3-diamine dihydrochloride, the publication is Journal of Molecular Modeling (2015), 21(10), 1-13, database is CAplus and MEDLINE.

The present work provides sets of correction factors to adjust the calculated vibrational frequencies of a series of ¦Á,¦Ø-diamines hydrochloride salts to account for the intermol. interactions with the counterion. The study was performed using different theory levels for predicting the vibrational data of isolated dicationic ¦Á,¦Ø-diamines and their hydrochloride forms, with and without the explicit account of the interactions with the chloride counterions. Different sets of correction factors were determined for each theory level considering the four smallest elements for the ¦Á,¦Ø-diamines series, while their transferability and reliability was evaluated considering the larger elements of the series. The theory level simplification was also evaluated and was found to neither compromise the vibrational frequencies estimates nor the magnitude and accuracy of the pre-defined scaling factors. This suggests that transferability of the correction factors is possible not only for different diamines but also between different levels of theory with the averaged group correction factor, ¦Æ^a_g, being the best choice to account for the effects of the N-H¡¤¡¤¡¤Cl interactions. The possibility of simplifying the theory level without compromising efficiency and accuracy is addnl. of utmost importance. This computational approach can constitute a valuable tool in the future for studying the hydrochloride forms of larger and more complex diamine systems.

Bhaskar Reddy, Manda published the artcileDesign and synthesis of Tr?ger’s base ditopic receptors: host-guest interactions, a combined theoretical and experimental study, SDS of cas: 10517-44-9, the publication is Organic & Biomolecular Chemistry (2015), 13(4), 1141-1149, database is CAplus and MEDLINE.

Two flexible Troeger base ditopic receptors C4TB and C5TB incorporating an aza-crown ether were designed and synthesized for bis[ammonium ion] complexation. A comprehensive study of host-guest interactions was established by ¹H NMR spectroscopy and DFT calculations Bis[ammonium chloride] with a short alkyl chain spacer showed the highest affinity for the receptors. M06-2X/cc-pVTZ calculations including the solvent effects on host-guest complexes were employed to explain and rationalize the exptl. trends. The short N-H¡¤¡¤¡¤O or N-H¡¤¡¤¡¤N hydrogen-bond distances observed in the range of 1.71-1.98 ? indicate the existence of a strong charge assisted hydrogen bonding between the host and the guest. The unusual behavior (higher binding constant) of A5 in ¹H NMR titration is traced to the conformational folding of the guest. The synthesis of the target compounds was achieved by a reaction of 1,4,7-trioxa-10-azacyclododecane and 1,4,7,10-tetraoxa-13-azacyclopentadecane with a bis(bromoethoxy)6H,12H-5,11-Methanodibenzo[b,f][1,5]diazocine derivative (Troger’s base).

Fripiat, Jose J. published the artcileAdsorption of amines by montmorillonites. III. Nature of the aminemontmorillonite bond, Formula: C3H12Cl2N2, the publication is Bulletin de la Societe Chimique de France (1962), 635-44, database is CAplus.

The complexes formed between Macid or Msatd. and C₆H₆ solutions of BuNH₂, PrNH₂, ethylenediamine and propylenediamine were studied by infrared spectroscopy. In the Macid complexes there are alkyl mono- and alkyl diammonium cations. Since the amount of adsorption of the diamines is larger than the exchange capacity of the montmorillonite, R(NH₃⁺)₂ becomes converted to the form of (NH₂)R(NH₃⁺). Neutral amine adsorption is identified in these complexes and is similar to that observed on Msatd. Spectroscopic evidence also supports the existence of 2 orientations for the C chains, parallel and perpendicular to the plane of the silicates. Addition of NaOMe to the monoamine complexes expels the amine but MeOH is trapped inside the lattice as it contracts. The infrared spectra of this material shows a pattern characteristic of solid MeOH. When NaOMe is added to the diamine complexes, there is only a partial lattice contraction and the infrared pattern shows pure MeOH vapor characteristics.

Grawe, Thomas published the artcileSelf-Assembly of Ball-Shaped Molecular Complexes in Water, Related Products of catalysis-chemistry, the publication is Journal of Organic Chemistry (2002), 67(11), 3755-3763, database is CAplus and MEDLINE.

The authors present a simple and versatile access to spheroidal mol. assemblies with pronounced stability in highly polar solvents. These complexes are composed of doubly and triply charged complementary building blocks based on ammonium or amidinium cations and phosphonate anions. Their high thermodn. stability is best explained by the formation of a cyclic array of alternating pos. and neg. charges interconnected by a regular network of H bonds. Association constants reach 10⁶ M^-1 in methanol and often surpass 10³ M^-1 in water. The broad range of binding energies correlates well with the varying degree of preorganization of both complex partners. As a byproduct of these studies, new recognition motifs for histidine and arginine esters and the unsubstituted guanidinium ion are proposed. The addnl. introduction of Me groups in the 2-, 4-, and 6-positions of the central benzene ring in either cations or anions causes a marked drop in the corresponding K_a values of 1 order of magnitude; the related rotational barriers were estimated at 0.3-2.1 kcal/mol. Spontaneous formation of defined 2:1 complexes from three components also was observed
