Jackson, S. David published the artcileAdsorption of chiral 2,2′-substituted-1,1′-binaphthalenes onto silica-supported palladium and nickel, Formula: C22H18O2, the publication is Adsorption Science & Technology (2006), 24(3), 257-267, database is CAplus.

The nature of the adsorption of 2,2′-substituted-1,1′-binaphthalenes over supported palladium and nickel catalysts were studied. Adsorption occurs through the 2,2′-substituted functional groups. Where this is not possible, no adsorption of the binaphthyl is observed Adsorption of 2,2′-diamino-1,1′-binaphthalene occurred solely on the metal components of the catalysts. However, total coverage of the metal surface was not obtained, with only specific sites being available for adsorption. Adsorption of 2,2′-dihydroxy-1,1′-binaphthalene occurred on the metal components but also spilled over onto the support. Adsorption was detected for 2-hydroxy-2′-methoxy-1,1′-binaphthalene but no spill-over was observed, indicating that both hydroxy groups are involved in the spill-over process. Co-adsorption and sequential adsorption studies revealed that there are a variety of adsorption sites that favor different binaphthyls.

Payagala, Tharanga published the artcileSynthesis and chromatographic evaluation of new polymeric chiral stationary phases based on three (1S,2S)-(-)-1,2-diphenylethylenediamine derivatives in HPLC and SFC, HPLC of Formula: 2960-93-2, the publication is Analytical and Bioanalytical Chemistry (2011), 399(7), 2445-2461, database is CAplus and MEDLINE.

Three new polymeric chiral stationary phases were synthesized based on (1S,2S)-1,2-bis(2,4,6-trimethylphenyl)ethylenediamine, (1S,2S)-1,2-bis(2-chlorophenyl)ethylenediamine, and (1S,2S)-1,2-di-1-naphthylethylenediamine via a simple free-radical-initiated polymerization in solution These monomers are structurally related to (1S,2S)-1,2-diphenylethylenediamine which is the chiral monomer used for the com. P-CAP-DP polymeric chiral stationary phase (CSP). The performance of these three new chiral stationary phases were evaluated in normal phase HPLC and supercritical fluid chromatog. and the results were compared with those of the P-CAP-DP column. All three new phases showed enantioselectivity for a large number of racemates with a variety of functional groups, including amines, amides, alcs., amino acids, esters, imines, thiols, and sulfoxides. In normal phase, 68 compounds were separated with 28 baseline separations (Rs �1.5) and in SFC, 65 compounds were separated with 24 baseline separations In total 72 out of 100 racemates were separated by these CSPs with 37 baseline separations Complimentary separation capabilities were observed for many analytes. The new polymeric CSPs showed similar or better enantioselectivities compared with the com. column in both HPLC and SFC. However, faster separations were achieved on the new stationary phases. Also, these polymeric stationary phases have good sample loading capacities while maintaining enantioselectivity.

Feng, Li-Heng published the artcileHighly selective recognition of monosaccharide based on two-component system in aqueous solution, Computed Properties of 2960-93-2, the publication is Tetrahedron (2011), 67(18), 3175-3180, database is CAplus.

A highly selective switch for D-fructose was formed by water-soluble conjugated polymer (PP-S-BINOL) and tetraboronic acid-functionalized benzyl viologen (ToBV). The two-component system showed a high selectivity and sensitivity only for D-fructose in familiar D-monosaccharides. The high selectivity of the sensing system for D-fructose may be depended on stable pyranose ester form of D-fructose with ToBV. A desirable linear response of the sensing system to low concentrations of D-fructose (<10.0 mM) was observed with 0.9936 linear dependent coefficient at pH 7.4.

Sun, Ping published the artcileEvaluation of aromatic-derivatized cyclofructans 6 and 7 as HPLC chiral selectors, Name: 2,2′-Dimethoxy-1,1′-binaphthalene, the publication is Analyst (Cambridge, United Kingdom) (2011), 136(4), 787-800, database is CAplus and MEDLINE.

The two best aromatic-functionalized cyclofructan chiral stationary phases, R-naphthylethyl-carbamate cyclofructan 6 (RN-CF6) and dimethylphenyl-carbamate cyclofructan 7 (DMP-CF7), were synthesized and evaluated by injecting various classes of chiral analytes. They provided enantioselectivity toward a broad range of compounds, including chiral acids, amines, metal complexes, and neutral compounds It is interesting that they exhibited complementary selectivities and the combination of two columns provided enantiomeric separations for 43% of the test analytes. These extensive chromatog. results provided useful information about method development of specific analytes, and also gave some insight as to the enantioseparation mechanism.

Hellinghausen, Garrett published the artcileImproving peak capacities over 100 in less than 60 seconds: operating above normal peak capacity limits with signal processing, Application In Synthesis of 2960-93-2, the publication is Analytical and Bioanalytical Chemistry (2020), 412(8), 1925-1932, database is CAplus and MEDLINE.

A primary focus in liquid chromatog. anal. of complex samples is high peak capacity separations Using advanced instrumentation and optimal small, high-efficiency columns, complex multicomponent mixtures can now be analyzed in relatively short times. Despite these advances, chromatog. peak overlap is still observed Recently, attention has shifted from improvements in chromatog. efficiency and selectivity to enhancing data processing after collection. Curve fitting methods can be used to trace underlying peaks, but do not directly enhance chromatog. resolution Methods based on the properties of derivatives and power transform were recently shown to enhance chromatog. peak resolution while maintaining critical peak information (peak areas and retention times). These protocols have been extensively investigated for their fundamental properties, advantages, and limitations, but they have not been evaluated with complex chromatograms. Herein, we evaluate the use of deconvolution via Fourier transform (FT), even-derivative peak sharpening, and power law with the fast separation (< 60 s) of a 101-component mixture using ultra-high-pressure liquid chromatog. High noise and peak overlap are present in this gradient separation, which is representative of fast chromatog. Chromatog. resolution enhancement is demonstrated and described. Further, accurate quantitation is maintained and shown with representative examples. Enhancements in peak capacity and peak-to-peak resolutions are discussed. Finally, the statistical theory of overlap is used for 101 peaks and predictions are made for the number of singlet, doublet, and multiplets analyte peaks. The effect of increasing peak capacity by FT even derivative sharpening and power laws leads to a decrease in the number of peak overlaps and an increase in total peak number

The homocoupling of aryl halides and the heterocoupling of aryl halides with either aryl bromides or arenes bearing an ortho-lithiation directing group are presented. The use of a Pd catalyst, in combination with t-BuLi, allows for the rapid and efficient formation of a wide range of polyaromatic compounds in a one pot procedure bypassing the need for the sep. preformation of an organometallic coupling partner. These polyaromatic structures were obtained in high yields, in 10 min at room temperature, with minimal waste generation (E-factors as low as 1.5) and without the need for strict inert conditions, making this process highly efficient and practical in comparison to classical methods. As illustration, several key intermediates of widely used BINOL-derived structures are readily prepared including the highly desired precursor to the chiral TRIP phosphoric acid.

Zhou, Qing-cheng published the artcileDesign and synthesis of PPV conjugated light-emitting polymers containing binaphthalene, Related Products of naphthyridine, the publication is Faguang Xuebao (2005), 26(4), 441-447, database is CAplus.

Conjugated polymers as light emitting materials have attracted considerable attention during the past several decades. There is substantial ongoing research towards the design of blue light emitting materials for OLEDs based on conjugated polymers. The conjugation length, steric hindrance within the polymer, must be controlled for such purpose. It is well known that the binaphthyl unit possesses a large dihedral angle ranging from 60° to 120°. Therefore, the conjugation of the binaphthyl-containing polymers can be interrupted by the highly twisted binaphthyl unit. In addition, the highly twisted structure will reduce the intermol. interaction of the polymers. As a result, the binaphthyl-containing polymers will have high quantum efficiency and good solubility Binaphthalene chromophores were introduced into the backbone of conjugated copolymers with different aromatic groups by Wittig or Wittig-Horner reaction, three linear copolymers and a hyperbranched copolymer containing binaphthyl unites were synthesized. All the copolymers were characterized by FT-IR, ¹H NMR. They were readily dissolved in the common solvents such as tetrahydrofuran(THF), dichloromethane, and chloroform. Their photophys. properties have been studied. The results indicated that all copolymers show pure blue light emitting. It is mentionable that the hyperbranched copolymer BN-TPPV shows the highest quantum efficiency (95%) among the four copolymers, which exhibits two emission band peaked at 393 nm and 410 nm in chloroform and one broad emission band peaked at 428 nm in solid film. Cyclic voltammetry was employed to investigated the electrochem. properties of the polymers, their band gaps were ranging from 2.76 eV to 3.05 eV, this result testified that the polymers, BN-PPV, BN-PBPV, BN-TPPV, have the potential to be applied as blue light emitting materials. The results show that it is a practical way to prepare blue light emitting polymers by incorporating binaphthyl into polymer chain.

The scope of the S_RN1 mechanism and the Stille reaction to synthesize 1,1′-binaphthalene derivatives was investigated. The best yield of 2′-methoxy-1,1′-binaphthalenyl-2-ol (52%) was obtained in liquid ammonia or DMSO by the S_RN1 irradiated reaction of 1-iodo-2-methoxynaphthalene with the anion of 2-naphthol. A lower yield (40%) of BINOL is obtained in water with 1-iodo-2-hydroxynaphthalene as substrate when the reaction is sonicated before irradiation The Stille reaction between (2-methoxy-1-naphthyl)-trimethylstannane and 1-iodo-2-methoxynaphthalene afforded low yields (15-11%) of the 1,1′-binaphthalene derivative Based on AM1 and B3LYP calculations the yields of the 1,1′-binaphthalene derivatives obtained through the electron transfer S_RN1 reaction can be attributed to kinetic factors of the radical nucleophile coupling step.
