Abstract:

An efficient naphthalene-based fluorescent probe (BTNA) for cysteine (Cys) has been rationally designed and synthesized in this work, which consists of a 6-(2-benzothiazolyl)-2-naphthalenol (BNO) fluorophore connected with an acrylate group (the fluorescence quenching and response group).

Abstract:

Essential oils extracted by hydrodistillation from leaves and roots of Ottoa oenanthoides Kunth (Apiaceae) were analyzed by GC/MS. The oils, obtained in yields of 0.10% and 0.66%, respectively, each contained four compounds, which were identified from their mass spectra and retention indices (RI). The major compound identified was 2-methoxy-8-methyl-1,4-naphthalindione (59.9% leaves, and 62.8%, roots), followed by 7-methoxy-1-naphthol (18.3% leaves and 17.3% roots), 2-naphthalenol (18.6% leaves and 15.0% roots), and 3-methoxy-2-naphthalenol (3.1% leaves and 2.1% roots).

Besides, the theoretical interaction of Strychnin‐oxiran‐naphthalenol derivatives (compounds 7 and 8) as noradrenaline and serotonin reuptake inhibitors was evaluated using two proteins (1ieo and 5i6z) as

Abstract A reverse phase liquid chromatographic (LC) system has been developed for separating the main naturally occurring carotenoids that have provitamin A activity.

The sulfonation of benzene-SO2X (X = CH3, OCH3, OH, and Cl) and of 1- and 2-naphthalene-SO2X (X = CH3, OCH3, and Cl) with sulfur trioxide in nitromethane as solvent has been studied. In the benzene series, substitution only occurs at the 3-position irrespective of X; the reaction rates, which are all within the same order of magnitude, are low. Upon sulfonation of the 1-SO2X-substituted naphthalenes, the main sulfonation product (58–80%) is the 5-sulfonic acid (5-S); in addition, 6-S and small amounts of 3-S and 7-S are formed.

Abstract:

Mono- and dinitro-BN-naphthalenes, i.e., 1-nitro-, 3-nitro-, 1,6-dinitro-, 3,6-dinitro-, and 1,8-dinitro-BNN, were generated in the nitration of 9,10-BN-naphthalene (BNN), a boron–nitrogen (BN) bond-embedded naphthalene, with AcONO2 and NO2BF4 in acetonitrile. The nitrated products were isolated and characterized by NMR, GC-MS, IR, and X-ray single crystallography. The effects of the nitration on the electron density and aromaticity of BNN were evaluated by B-11 NMR analysis and HOMA calculations.

Abstract:

The charge-transfer band of syn-9-methoxy(1,4)naphthaleno[3.3]metacyclophanes with tetracyanoethylene in CH2Cl2 are observed in the range of 604–606 nm, which is arising from the exclusive formation on the naphthalene ring due to the expanded π-electron density as well as the steric hindrance of the inner methoxy group at 9-position.

Abstract:

4,8-Dimethoxy-5-(tosyloxy)-1-naphthaldehyde (1) and 8-methoxy-5-(tosyloxy)-1-naphthaldehyde (2) crystallize such that the formyl groups approach coplanarity with the naphthalene rings. 4′,8′-Dimethoxy-5′-(tosyloxy)-1′-acetonaphthone (4), however, crystallizes such that the acetyl group approaches orthogonality to the naphthalene ring. In all three compounds the methoxy group and carbonyl groups exhibit a leaning effect typical of nucleophile–electrophile interactions in 1,8-disubstituted naphthalenes. 8-(Benzoyloxy)-4-methoxy-1-naphthaldehyde (3) crystallizes with the formyl group nearly copla

Polychlorinated naphthalenes (PCNs) consist of 75 potential congeners in eight homologous groups. PCNs are toxic, resist decomposition, and bioaccumulate in adipose tissue. They are transported through air, water, and migratory birds, across international borders and precipitate far from place. Released, where they accumulate in terrestrial and aquatic ecosystems, PCNs form as unintended persistent organic pollutants (UPOPs) with PCDDs, PCDFs, PCBs, and other UPOPs.

Solid–liquid binary phase diagrams and isothermal unit-cell parameters as a function of composition are given for the high-temperature form (P21/a,Z= 2) mixed crystals generated by 2-fluoronaphthalene, naphthalene and 2-naphthol with four other β derivatives of naphthalene. The study leads to the distinction between two high-temperature forms (or types of packing). The first one (type 1) is taken by five 2-R-naphthalenes (R= F, Cl, Br, SH, CH3; the first subfamily), the second one (type 2) by naphthalene itself and 2-naphthol (R= H, OH; the second subfamily).

A bacterial strain, QWE-5, which utilized naphthalene as its sole carbon and energy source, was isolated and identified as Streptomyces sp. It was a Gram-positive, spore-forming bacterium with a flagellum, with whole, smooth, convex and wet colonies. The optimal temperature and pH for QWE-5 were 35 °C and 7.0, respectively. The QWE-5 strain was capable of completely degrading naphthalene at a concentration as high as 100 mg/L. At initial naphthalene concentrations of 10, 20, 50, 80 and 100 mg/L, complete degradation was achieved within 32, 56, 96, 120 and 144 h, respectively. Kinetics of napht

Abstract:

The distributions of methylated naphthalenes in crude oils carry within them detailed information regarding the geological history of the oils. The effects of thermal stress, mixing, biodegradation and migration contamination all leave recognisable imprints, which can be deconvoluted. An extended suite of crude oils from several locations in Australia was analysed for their methylated naphthalene content. It was shown that three ratios of selected isomers, each reflecting the same underlying sedimentary reactions, are linearly related to each other when thermal stress has been the only factor
