《Photocatalytic selective aerobic oxidation of amines to nitriles over Ru/γ-Al2O3: the role of the support surface and the strong imine intermediate adsorption》 was written by Zhu, Pengqi; Zhang, Jin; Wang, Jie; Kong, Peng; Wang, Yunwei; Zheng, Zhanfeng. Application In Synthesis of 4-Fluorobenzonitrile And the article was included in Catalysis Science & Technology in 2020. The article conveys some information:

Hydroxyl coordinated ruthenium dispersed on the surface of γ-Al2O3 can be applied to the selective oxidation of amines with light irradiation and an atm. pressure of O2 at room temperature Sunlight is also an effective light source for the selective aerobic oxidation of primary amines to corresponding nitriles. The high photocatalytic activity and selectivity over Ru/γ-Al2O3 originate from the adsorption of amines and imine intermediates on the abundant surface OH groups of the photocatalyst and further formation of Ru-amide species by ligand exchange of adsorbed amines and imine intermediates with adjacent exposed active Ru sites. Light is introduced to the system successfully via the formation of Ru-amide species, which are used as the light absorption sites of the photocatalytic selective oxidation of amines. Primary amines are directly converted to corresponding nitriles via a two-step oxidative dehydrogenation process.4-Fluorobenzonitrile(cas: 1194-02-1Application In Synthesis of 4-Fluorobenzonitrile) was used in this study.

Aldosterone synthase (CYP11B2) inhibitors have been explored in recent years as an alternative therapeutic option to mineralocorticoid receptor (MR) antagonists to reduce elevated aldosterone levels, which are associated with deleterious effects on various organ systems including the heart, vasculature, kidney, and central nervous system (CNS). A benzamide pyridine hit derived from a focused screen was successfully developed into a series of potent and selective 3-pyridyl isoindolin-1-ones CYP11B2 inhibitors. Our systematic structure-activity relationship study enabled us to identify unique structural features that result in high selectivity against the closely homologous cortisol synthase (CYP11B1). We evaluated advanced lead mols., exemplified by compound 52, in an in vivo cynomolgus monkey acute adrenocorticotropic hormone (ACTH) challenge model and demonstrated a superior 100-fold in vivo selectivity against CYP11B1.

The article was titled 《Solvatochromism, tautomerism and dichroism of some azoquinoline dyes in liquids and liquid crystals》. The information in the text is summarized as follows:

Absorption and emission spectra of three hetarylazoquinoline compounds with different substituents were examined in liquids and liquid crystalline solvents for the first time. The spectral features of the hetarylazoquinoline dyes were explained according to azo/hydrazone tautomerism in conjunction with the solvatochromic characteristic of the preferred tautomer. The nature and extent of solute-solvent interactions were described using Kamlet-Taft and Katritzky multiparameter polarity scales. Solvatochromic azo/hydrazone tautomerism depend on multiple solute-solvent interactions, in particular on specific interactions and the solvent ability to transport the hydrogen atom through the media. In addition, anisotropic hosts prevent shift of the tautomeric equilibrium toward the hydrazone form.

Reference of 4-Cyano-3-fluorophenyl 4-butylbenzoateOn September 26, 1984 ,《The synthesis and transition temperatures of benzoate ester derivatives of 2-fluoro-4-hydroxy- and 3-fluoro-4-hydroxybenzonitriles》 was published in Helvetica Chimica Acta. The article was written by Kelly, Stephen M.. The article contains the following contents:

2-FC6H4OMe was brominated in CHCl3 to 92% 2,4-FBrC6H3OMe which was cyanated to 58% 3,4-F(MeO)C6H3CN. This was demethylated with AlCl3-NaCl to 66% 3,4-F(HO)C6H3CN which was esterified with 4-Me(CH2)4C6H4COCl in PhMe to 62% I [R = Me(CH2)4]. Prepared by the same procedure were 59 other ethers I-IV (R = alkyl, alkoxy). The nematic-isotropic liquid transition temperatures of most of these model esters are only slightly lower than those of the corresponding esters having a H atom in place of F. In several cases, the clearing points of the fluorophenyl esters are higher than those of the unsubstituted Ph esters. The nematic ranges of several of the new esters are markedly broader than those of the analogous non-F substituted Ph esters. In the experiment, the researchers used many compounds, for example, 4-Cyano-3-fluorophenyl 4-butylbenzoate(cas: 86776-52-5Reference of 4-Cyano-3-fluorophenyl 4-butylbenzoate)

For 4-cyano-3-fluorophenyl 4-butylbenzoate, nematic glass former at ambient pressure, dielec. relaxation studies were performed under elevated pressure. In the isobaric experiment, on cooling the nematic phase two super-Arrhenius α-relaxations, ascribed to the reorientations of mols. around short axes and precession of long mol. axes were found and the Arrhenius β-relaxation related to intramol. motions. Complexity of dynamics at elevated and ambient pressure is similar.
