Determination of Missing Crystal Structures in the 1 Alkyl-3-methylimidazolium Hexafluorophosphate Series: Implications on Structure-Property Relationships was written by Endo, Takatsugu;Masu, Hyuma;Fujii, Kozo;Morita, Takeshi;Seki, Hiroko;Sen, Sabyasachi;Nishikawa, Keiko. And the article was included in Crystal Growth & Design in 2013.Electric Literature of C7H13ClN2 This article mentions the following:

The authors have performed single crystal X-ray diffraction analyses of two 1-alkyl-3-methylimidazolium hexafluorophosphate ([C_nmim]-PF₆) salts, [C₁mim]-PF₆, and [C₃mim]-PF₆. The thermodynamically metastable crystalline phase (尾 phase) of the former was obtained by crystallization from the melt in a capillary for the crystallog. anal. Both the cation and the anion in the 尾 phase of [C₁mim]-PF₆ show higher point group symmetry than those in the stable 伪 phase. This result is shown to be consistent with the fact that the m.p. of the 尾 polymorph (314 K) is significantly lower than that of the 伪 polymorph (364 K). The crystal structure of [C₃mim]-PF₆ seems to be typical of that characteristic of the crystals of imidazolium-based room temperature ionic liquids The cation conformation is the one in between those characteristic of the crystal structures of [C₂mim]-PF₆ and [C₄mim]-PF₆. When taken together, all crystallog. data for the [C_nmim]-PF₆ series (n = 1-4) demonstrate the influence of the alkyl chain length dependence on structural packing in these salts. The free volume fractions for these structures are calculated and compared to the lattice energy simply based on formula unit volume It is shown that the difference in the alkyl chain length of the imidazolium cations does not monotonically change with the lattice energy of the crystal structure, and the latter also depends on the packing efficiency of the constituent ions in the structure.

Mechanisms of N-substitution in glyoxaline derivatives. I. Introduction, and study of prototropic equilibria involving 4(5)-nitroglyoxaline was written by Grimison, A.;Ridd, J. H.;Smith, B. V.. And the article was included in Journal of the Chemical Society in 1960.Application In Synthesis of 1-Methyl-4-nitroimidazole This article mentions the following:

The orientation of N-substitution in glyoxaline derivatives was discussed in terms of the reaction mechanism and the tautomeric equilibria involved. A spectrometric study of acid-base equilibria in aqueous solutions of 4(5)-nitroglyoxaline (I) and its N-Me derivatives was reported. The basicity of the 1,5-methyl derivative (II) was greater than that of I, but the basicity of the 1,4-isomer (III) was less; these results were related to the position of tautomeric equilibrium in the parent compound A small ionic strength correction was made to obtain the thermodynamic pK values as follows (compound, medium, form, 位 max in m渭, 10^-3蔚, and pK values given): I, 0.1M NaOH, conjugate base, 350, 10.19, -; I, buffer pH 4.7, neutral molecule, 297, 6.40, 9.30; I, 5M HClO₄, conjugate acid, 269, 7.04, -0.05; II, H₂O, neutral, 303, 8.37, -; II, M HClO₄, conjugate acid, 266, 6.42, 2.13; III, H₂O, neutral, 300, 7.27, -; III, 5M HClO₄, conjugate acid, 269, 7.16, -0.53. The following indicator values were obtained based on optical ds. at 300 and 310 m渭. The spectra of the neutral mols. and the conjugate acids used in these calculations were obtained in the above conditions. A small correction was applied to the spectrum of III in 5M HClO₄, because about 2% of the neutral molecule should then be present. The protonation of I and III in mineral acids gave the following values (molarity of acid and the log ([GH₂⁺]/[GH]) for I in HClO₄, in HCl, for III in HClO₄, in HCl given): 0.25, -0.63, -, -1.02, -; 0.50, -0.25, -, -0.69, -0.75; 0.75, -0.05, -, -0.40, -0.54; 1.0, 0.18, 0.02, -0.23, -0.40; 1.3, 0.30, 0.13, -0.04, -; 1.5, 0.44, 0.24, -, 0.09; 1.6, -, -, -0.12, -; 2.0, 0.74, 0.43, 0.34, 0.08; 2.5, 0.90, 0.67, 0.53, 0.25; 3.0, 1.20, -, 0.75, 0.40. The S脢2′ mechanism appeared to occur much more readily than the S脢2 mechanism for substitution in derivatives of glyoxaline. For substitution in a glyoxaline derivative, it was easy to show that the orientation depended on the mechanism involved. The neutral mol. of I existed in solution as an equilibrium mixture of 2 tautomeric forms, both of which could lose or add a proton to form the common conjugate acid and conjugate base. The pK was determined by plotting log ([GH₂+]/[GH])-log-[H⁺] against the molarity of the acid and extrapolating to zero concentration The linear extrapolation to obtain the pK was given in a figure. The basicity of the N-methylnitroglyoxalines was studied. III was a little less basic than I. The protonation was followed in the same way II was much more basic than I and the equilibrium was studied in buffer solutions The extent to which the protonation of substituted glyoxalines followed the acidity function H₀ was of interest because glyoxalines were very different in structure from the aniline derivatives used in estimating the H₀ scale. Some values were given above for I and III. From such comparisons it seemed that the protonation of I followed H₀ in HClO₄, but deviated appreciably from H₀ in HCl. In both acids the protonation of III increased more rapidly with acidity than did I. In the experiment, the researchers used many compounds, for example, 1-Methyl-4-nitroimidazole (cas: 3034-41-1Application In Synthesis of 1-Methyl-4-nitroimidazole).

And the article was included in Bioorganic & Medicinal Chemistry in 2016.Safety of 1-Methyl-1H-benzo[d]imidazole-2-carbaldehyde This article mentions the following:

In search of more effective chemotherapeutics for the treatment of castration-resistant prostate cancer and inspired by curcumin analogs, twenty five (1E,3E,6E,8E)-1,9-diarylnona-1,3,6,8-tetraen-5-ones bearing two identical terminal heteroaromatic rings have been successfully synthesized through Wittig reaction followed by Horner-Wadsworth-Emmons reaction. Twenty-three of them are new compounds The WST-1 cell proliferation assay was employed to assess their antiproliferative effects toward both androgen-sensitive and androgen-insensitive human prostate cancer cell lines. Eighteen out of twenty-five synthesized compounds possess significantly improved potency as compared with curcumin. The optimal compound, I, is 14- to 23-fold more potent than curcumin in inhibiting prostate cancer cell proliferation. It can be concluded from the data that 1,9-diarylnona-1,3,6,8-tetraen-5-one can serve as a new potential scaffold for the development of antiprostate cancer agents and that pyridine-4-yls and quinolin-4-yl act as optimal heteroaromatic rings for the enhanced potency of this scaffold. Two of the most potent compounds, II and III, effectively suppress PC-3 cell proliferation by activating cell apoptosis and by arresting cell cycle in the G₀/G₁ phase.

And the article was included in Carbohydrate Polymers in 2013.Recommanded Product: 35487-17-3 This article mentions the following:

A novel adsorbent, biodegradable collagen/cellulose hydrogel beads (CCHBs), was prepared by reconstitution from a 1-Bu, 3-methylimidazolium chloride ([C₄mim]Cl) solution The adsorption properties of the CCHBs for Cu(II) ion removal from aqueous solutions were investigated and compared with those of cellulose hydrogel beads (CHBs). The CCHBs have a three-dimensional macroporous structure whose amino groups are believed to be the main active binding sites of Cu(II) ions. The equilibrium adsorption capacity (q_e) of the CCHBs is greatly influenced by the collagen/cellulose mass ratio, and steeply increases until the collagen/cellulose mass ratio exceeds 2/1. The maximum adsorption is obtained at pH 6. The q_e of Cu(II) ions increases with increased initial concentration of the solution Based on Langmuir isotherms, the maximum adsorption capacity (q_m) of CCHB3 (collagen/cellulose mass ratio of 3/1) is 1.06 mmol/g. The CCHBs maintain good adsorption properties after the fourth cycle of adsorption-desorption.
