This manuscript studies the fluorescent property of 3-[(2-hydroxy-1-naphthyl)methylideneamino]benzoic acid (H2L). Fluorescent spectra show that in different solvents, H2L displays different fluorescent properties, which can be attributed to the interaction between the solvents and H2L. Further s...
The regioselectivity in Pd(II)-catalyzed CH direct functionalization of C2-substituted naphthalenes has been a long-term issue in synthetic organic chemistry due to its existence of competitive reaction sites, including C1-, C3- and even C4-sites. Our recent achievement in Pd(II)-catalyzed C1-de...
New approach to synthesis of tri(1-naphthyl)phosphine (Np3P) and its application for design of new Pd(II) and Cu(I) complexes are reported. This phosphine has been prepared in 32% yield through exhaustive P–H arylation of РН3 with 1-chloronaphthalene in the superbasic t-BuOK/DMSO system at 70...
The versatile precursor 2-acetyl-4-allyl-1-hydroxy naphthalene was synthesized efficiently via Claisen rearrangement 2-acetyl-1-allyloxynaphthalene. The Claisen-Schmidt condensation of latter precursor afforded the corresponding chalcones which were exploited to synthesize a series of potential ...
In the present work, a series of cyclotriphosphazenes containing 1-naphthyl derivatives (3, 4, 5, 7, 8 and 9) was synthesized. Mono-(3), geminal bis-(4) and tetrakis (5) 1-naphthylamino substituted cyclotriphosphazenes were synthesized from the reactions of hexachlorocyclotriphosphazene (N3P3Cl6...
Isothermal titration calorimetry, UV optical melting, differential scanning calorimetry, circular dichroism and ethidium bromide displacement experiments were employed to study the interaction of the polyamine analogue 1-naphthyl acetyl spermine with DNA. The mode of binding was evaluated by hoe...
A highly active solid acid was prepared by impregnating trifluoromethanesulfonic acid (TFMSA) onto mesostructured zirconium oxide (MSZO). Di(1-naphthyl)methane (DNM) was used as a coal-related model compound to evaluate the catalytic activity of TFMSA/MSZO for cleaving strong C–C bridged bonds ...
A new solid acid was prepared by trifluoromethanesulfonic acid (TFMSA) impregnation into an acid-treated attapulgite (ATA). Di(1-naphthyl)methane (DNM) hydrocracking was used as the probe reaction to evaluate the catalytic performance of TFMSA/ATA for cleaving Car–Calk bridged bonds in coals. T...
Catalysts trifloromethanesulfonic acid (TFMSA)/treated attapulgite powder (TAP), Ni/TAP, and Ni-TFMSA/TAP with different Ni and TFMSA loadings were prepared. The typical catalysts were characterized with multiple instruments and used for catalyzing hydroconversion of di(1-naphthyl)methane (DNM),...
The synthesis and spectroscopic characterization of diorganotin(IV) bis(difluorobenzoates) [F2C6H3COO]2SnR2 [type a] and bis[diorgano(difluorobenzoato)tin(IV)] oxides {[(F2C6H3COO)R2Sn]2O}2 [type b] are described. An X-ray structure study has revealed compound 3b, {[(2,6-F2C6H3COO)(n-C4H9)2Sn]2O...
A series of chiral amino oxazolines were synthesized and screened as organocatalysts for asymmetric intermolecular aldol reactions between acetone and aromatic aldehydes. The reaction works well with a range of aromatic aldehydes showing good to high selectivity. The present new system of the or...
Fatty acid amide hydrolase (FAAH) and monoglyceride lipase (MGL) are the main enzymes responsible for the hydrolysis of endogenous cannabinoids N-arachidonoylethanolamide (AEA) and 2-arachidonoylglycerol (2-AG), respectively. Phenyl alkylcarbamates are FAAH inhibitors with anxiolytic and analges...
The solubilities of N-hydroxymethyl acrylamide were measured in pyridine, furan, acetonitrile, ethyl acetate, butyl acetate, toluene, chloroform, dichloromethane in temperatures ranging from 277.55 K to 342.45 K at atmospheric pressure using a laser detecting system. The solubility data were cor...
Candida albicans is considered as the primary etiologic agent of candidiasis, a very common fungal infection in human. The yeast to hyphal transition and ability to form hypoxic biofilm on medical devices is well allied with virulence and antifungal resistance of C. albicans. Antagonistic agents...
While optimizing the synthesis of pharmaceutical building block 3 [ethyl 1-(hydroxymethyl)-1,3-dihydroisobenzofuran-1-carboxylate], we encountered an unusual addition of an aryllithium reagent to the ketone oxygen atom of diethyl ketomalonate. Compound 3 was ultimately prepared on a large scale ...
During 2011–2014, we measured 3H concentrations in river water samples collected during base flow conditions and during several flood events from two small rivers in a mountainous area in Fukushima Prefecture, which received deposition of 137Cs from the Fukushima Dai-ichi Nuclear Power Plant ac...
The KBS-3H disposal alternative is composed by horizontally placed supercontainers comprising the canisters with the spent nuclear fuel surrounded in both drift axis and radial directions by compacted bentonite blocks (buffer) enclosed in a perforated shell. The different internal gaps between t...
Synergy between water, a green reaction medium and ionic liquid, a green catalyst has opened new vistas in the field of organic transformation. The developed methodology has emerged as an interesting combination for an environmentally benign, facile and efficient synthesis of benzothiazole-2(3H)...
Molecular dynamics simulation on the reaction of nano-aluminum particle and water were performed by ReaxFF force field. The different reaction rates of aluminum with H2O and D2O indicate that the effect of kinetic isotope effect (KIE) is obvious. The generation rate of H2 is 20% higher than that...
The isotope (δD, δ18O, 3H, δ13C, 14C) and chemical (B, Cl) compositions of cold (streams, rivers, soil- and groundwater) and low-temperature geothermal water from northern Iceland were investigated in order to delineate the origin, mixing, water-rock interaction and the age of the waters. The...
