The anion binding properties of 2,2′-dihydroxy-1,1′-binaphthalene (BINOL) derivatives were studied by ¹H NMR spectroscopy. BINOL derivatives formed complexes with anions through hydrogen bonding of the hydroxyl groups and showed a binding preference to dihydrogen phosphate (H₂PO₄^–) and acetate (AcO^–) in comparison with other anions (Cl^–, Br^–, I^–, NO₃^–, and HSO₄^–) tested.

Tu, Tao published the artcileRobust Acenaphthoimidazolylidene Palladium Complexes: Highly Efficient Catalysts for Suzuki-Miyaura Couplings with Sterically Hindered Substrates, Application of 2,2′-Dimethoxy-1,1′-binaphthalene, the publication is Organic Letters (2012), 14(16), 4250-4253, database is CAplus and MEDLINE.

Robust acenaphthoimidazolylidene palladium complexes I [R = i-Pr, R’= H; R = R’ = Me, H] have been demonstrated as highly efficient and general catalysts for the sterically hindered Suzuki-Miyaura cross-coupling reactions in excellent yields even with low catalyst loadings under mild reaction conditions. The high catalytic activity of these complexes highlights that, besides the “flexible steric bulky” concept, σ-donor properties of the NHC ligands are also crucial to accelerate the transformations.

Morioka, Kohei published the artcileSynthesis and chiral recognition ability of optically active poly{N-[(R)-α-methoxycarbonylbenzyl]methacrylamide} with various tacticities by radical polymerization using Lewis acids, Name: 2,2′-Dimethoxy-1,1′-binaphthalene, the publication is Journal of Polymer Science, Part A: Polymer Chemistry (2003), 41(21), 3354-3360, database is CAplus.

The radical polymerization of an optically active methacrylamide, N-[(R)-α-methoxycarbonylbenzyl]methacrylamide, was carried out in the absence and presence of Lewis acids such as ytterbium trifluoromethanesulfonate [Yb(OTf)₃] and scandium trifluoromethanesulfonate [Sc(OTf)₃]. Catalytic amounts of the Lewis acids significantly affected the stereoregularity of the obtained polymers. The polymerization with Yb(OTf)₃ in THF afforded isotactic polymers (up to mm = 87%), whereas the conventional radical method without the Lewis acid produced polymers rich in syndiotacticity (up to rr = 88%). The radical polymerization in the presence of MgBr₂ proceeded in a heterotactic-selective manner (mr = 63%). Thus, the isotactic, syndiotactic, and heterotactic poly(methacrylamide)s were synthesized by the radical processes. The chiral recognition abilities of the obtained optically active poly(methacrylamide)s were affected by the stereoregularity.

Paddon, Christopher A. published the artcileCoulometry on the voltammetric timescale: microdisk potential-step chronoamperometry in aprotic solvents reliably measures the number of electrons transferred in an electrode process simultaneously with the diffusion coefficients of the electroactive species, Product Details of C22H18O2, the publication is Electroanalysis (2007), 19(1), 11-22, database is CAplus.

Microdisk, single potential-step chronoamperometry, is applied to a range of organic substrates in the aprotic solvents THF, propylene carbonate, MeCN and the room temperature ionic liquid [C₄dmim][N(Tf)₂] (1-butyl-2,3-dimethylimidazolium bis(trifluoromethylsulfonyl)imide). Fitting of the chronoamperometric transients was achieved using the Shoup and Szabo method. Accurate values for the diffusion coefficients, D, and the number of electron(s) transferred, n, in the electrode process were simultaneously and consistently obtained. This method is generally applicable and reliable for the determination of the number of electrons transferred in faradaic processes uncomplicated by relatively slow coupled homogeneous kinetics. Since the experiment is conducted essentially on typical voltammetric timescales it can be commended as a complementary technique for classical coulometry which is only possible on much longer timescales. The chronoamperometric method is therefore likely to be of greater relevance to the interpretation of voltammetric data.

Genaev, Alexander M. published the artcileAcid-Catalyzed Versus Thermally Induced C1-C1′ Bond Cleavage in 1,1′-Bi-2-naphthol: An Experimental and Theoretical Study, Recommanded Product: 2,2′-Dimethoxy-1,1′-binaphthalene, the publication is Journal of Organic Chemistry (2019), 84(11), 7238-7243, database is CAplus and MEDLINE.

Experiments show that 1,1′-bi-2-naphthol (BINOL) undergoes facile C1-C1′ bond cleavage under action of triflic acid at temperatures above 0 °C to give mainly 2-naphthol along with oligomeric material. CASSCF and MRMP//CASSCF computations have demonstrated unambiguously that this unusual mode of scission of the biaryl bond can occur in the C1,C1′-diprotonated form of BINOL via a mechanism involving homolytic cleavage prompted by the intramol. electrostatic repulsion. These findings also provide insights into the mechanism of a comparatively easy thermal cleavage of BINOL, implying the intermediacy of its neutral diketo form.

A new benzo[c]carbazolyl-based phosphine ligand I has been designed and synthesized. This newly developed ligand I efficiently facilitates the Pd-catalyzed syntheses of tetra-ortho-substituted biaryl compounds RR¹ [R = C₆F₅, 2,3-dimethoxynaphthalen-1-yl, dimethyl-1,2-oxazol-4-yl, etc.; R¹ = 2,6-(CH₃)₂C₆H₃, 2,6-(CH₃O)₂C₆H₃, 2,4,6-(CH₃)₃C₆H₂, 2,6-(CH₃)₂-4-H₃COC₆H₂, 2-methoxynaphthalen-1-yl] via Suzuki-Miyaura cross-coupling. With 1 mol% of the Pd(OAc)₂/I catalyst, sterically congested biaryls were afforded in good-to-excellent yields. In particular, the mild reaction conditions exhibited good compatibility of heterocycles and functional groups including esters and nitrile. The ligand I was structurally characterized by X-ray crystallog. anal.

The first nickel-catalyzed alkenylation of unactivated C(sp³)-H bonds with vinyl iodides is described. The catalytic system comprises an inexpensive and air-stable Ni(acac)₂ as the catalyst and BINOL as the ligand, which is highly efficient for the alkenylation of β-Me C(sp³)-H bonds of a broad range of aliphatic carboxamides. The resulting olefins can serve as versatile handles for further preparation Addnl., we also demonstrated the synthesis of functionalized carboxamides bearing α-quaternary carbon centers from simple pivalamide via nickel-catalyzed sequential C(sp³)-H bond functionalization.

A post-synthetic transmetalation self-assembly strategy was developed for the preparation of near IR (NIR) emitting Yb₈L₆ cubes, which could not be synthesized through direct metal-ligand assembly procedures. Metal-adaptive critical structural transformations from La₆L₃ triangular prism to Ln₈L₆ cubes were observed along the lanthanide series, the latter of which showed size-selective guest binding behavior toward poly-aromatic hydrocarbon (PAH) mols.

A series of new biphenyl N,P-monophosphine ligands were developed via introduction of two methoxy groups to the biphenyl backbone. The ligands were found to be much more effective than their counterparts Buchwald ligands in the Suzuki-Miyaura coupling reactions of sterically hindered and electron-rich aryl chlorides with aryl boronic acids. A variety of tri-ortho-substituted or tetra-ortho-substituted biaryls or hetero-biaryls were conveniently prepared in up to 99% yield using 2′-(diphenylphosphanyl)-6,6′-dimethoxy-N,N-dimethyl-[1,1′-biphenyl]-2-amine-[Pd₂(dba)₃] as the catalyst.

Zhu, Junchen published the artcileA novel C₂ symmetric chiral stationary phase with N-[(4-Methylphenyl)sulfonyl]-L-leucine as chiral side chains, Computed Properties of 2960-93-2, the publication is Journal of Separation Science (2020), 43(12), 2338-2348, database is CAplus and MEDLINE.

In this study, a series of chiral stationary phases based on N-[(4-methylphenyl)sulfonyl]-L-leucine amide, whose enantiorecognition property has never been studied, were synthesized. Their enantioseparation abilities were chromatog. evaluated by 67 enantiomers. The chiral stationary phase derived from N-[(4-methylphenyl)sulfonyl]-L-leucine showed much better enantioselectivities than that based on N-(4-methylbenzoyl)-L-leucine amide. The construction of C₂ sym. chiral structure greatly improved the enantiorecognition performance of the stationary phase. The C₂ sym. chiral stationary phase exhibited superior enantioresolns. to other chiral stationary phases for most of the chiral analytes, especially for the chiral analytes with C₂ sym. structures. By comparing the enantioseparations of the enantiomers with similar structures, the importance of hydrogen bond interaction, π-π interaction, and steric hindrance on enantiorecognition was elucidated. The enantiorecognition mechanism of trans-N,N’-(1,2-diphenyl-1,2-ethanediyl)bis-acetamide, which had an excellent separation factor on the C₂ sym. chiral stationary phase, was investigated by ¹H-NMR spectroscopy and 2D ¹H-¹H nuclear overhauser enhancement spectroscopy.
