Transplacental naphthalene poisoning

American Journal of Obstetrics and Gynecology, 1959
Abstract The diagnosis of hemolytic anemia in a newborn infant secondary to maternal ingestion of moth balls is reported. The acute hemolytic anemia seen in this child apparently originated in utero due to transplacental migration of naphthalene and/or its oxidation products.

Directed ortho metalation strategies. Effective regioselective routes to 1,2-, 2,3-, and 1,2,3-substituted naphthalenes.

Organic Letters, 2014
The regioselective synthesis of 2,3-di- and 1,2,3-trisubstituted naphthalenes via Directed ortho Metalation (DoM) strategies of N,N-diethyl-O-naphthyl-2-carbamate (1) is presented.

NO binding to naphthalene dioxygenase

JBIC Journal of Biological Inorganic Chemistry, 2005
Nitric oxide (NO) is commonly used as an analogue for dioxygen in structural and spectroscopic studies of oxygen binding and oxygen activation. In this study, crystallographic structures of naphthalene dioxygenase (NDO) in complex with nitric oxide are reported.

Au(I)-catalyzed triple bond alkoxylation/dienolether aromaticity-driven cascade cyclization to naphthalenes.

Chemical Communications, 2014
A novel strategy for the synthesis of multisubstituted naphthalenes was developed via a Au(i)-catalyzed alkyne alkoxylation/dienolether aromaticity-driven cascade cyclization using 1,5-enyne substrates.

Comparison of the Toxicity of Naphthalene and Naphthalene-1,2-Dihydrodiol (DIOL)

1991
Naphthalene metabolism and toxicity have been extensively investigated and these data indicate that the lung and eye toxicity are mediated by reactive intermediates. The elegant studies conducted in Buckpitt’s laboratory implicate a 1,2-epoxide as one reactive intermediate which is extensively conjugated with glutathione (Buckpitt et al., 1987).

Occupational exposure to polychlorinated dibenzo-p-dioxins and dibenzofurans, dioxin-like polychlorinated biphenyls, and polychlorinated naphthalenes in workplaces of secondary nonferrous metallurgical facilities in China.

Environmental Science and Technology, 2013
The concentrations of polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs), dioxin-like polychlorinated biphenyls (dl-PCBs), and polychlorinated naphthalenes (PCNs) were determined in workplace air from eight secondary nonferrous metal ...

Three-bond breaking of cyclic anhydrides: easy access to polyfunctionalized naphthalenes and phenanthrenes.

Organic Letters, 2013
Benzannulation of phthalic anhydrides with alkynes to polyfunctionalized naphthalenes and phenanthrenes was confirmed to be straightforward using a palladium catalytic system.

Is chlorination one of the major pathways in the formation of polychlorinated naphthalenes (PCNs) in municipal solid waste combustion?

Environmental Science and Technology, 2013
The chlorination patterns of unsubstituted naphthalene were studied using a laminar flow reactor with a 1 cm particle bed of 0.5% (mass) copper(II) chloride (CuCl2) mixed with silicon dioxide (SiO2), operated over a temperature range of 100 to 400 °C and

One-pot synthesis of substituted tetrahydrocyclobuta[a]naphthalenes by domino aldol condensation/olefin migration/electrocyclization.

Organic Letters, 2013
A facile one-pot synthetic route for preparing the novel benzofused tricyclic skeleton of 1,2,2a,8b-tetrahydrocyclobuta[a]naphthalenes 5 is developed. The route was realized by a NaH-mediated tandem aldol condensation/olefin migration/electrocyclization ...

Photon-echo decay of naphthalene in durene and perdeutero-naphthalene

Chemical Physics Letters, 1978
Abstract Using two frequency-doubled, nitrogen laser pumped, dye-lasers we have measured the decay of the photon-echo in the lowest 1B1u ← 1A1g singlet state of naphthalene in durene and in perdeutero-naphthalene. Optical phase relaxation in the durene mixed crystal is believed to be caused by resonant phonon scattering in the ground and excited ...
