The Transisopropylation of Naphthalene [PDF]
Bulletin of the Chemical Society of Japan, 1975 Abstract The transisopropylation of naphthalene with p-cymene and isopropylxylenes in the presence of aluminum chloride–nitromethane complex as a catalyst was studied. It was observed that the α-isomer initially formed was isomerized to the β-isomer in the reaction with isopropyl-p-xylene. However, when p-cymene or isopropyl-o-xylene was

Mono- and Dinitro-BN-Naphthalenes: Formation and Characterization
Molecules, 2021 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 ...

Naphthalene plasmids in pseudomonads [PDF]
Journal of Bacteriology, 1982 A rapid method beginning with the direct lysis of bacteria in alkaline sodium dodecyl sulfate was used to detect naphthalene plasmids in pseudomonads. The strains NCIB 9816, PG, ATCC 17483, and ATCC 17484, which can grow on naphthalene as the sole source of carbon and energy, were examined. All except ATCC 17483 contained more than one plasmid.

1-(Benzyloxy)naphthalene [PDF]
Acta Crystallographica Section E Structure Reports Online, 2011 In the title compound, C(17)H(14)O, the dihedral angle between the naphthyl ring system and the benzyl group is 83.22 (4)°. Both of these moieties are planar, with mean deviations from their least-squares planes, defined by the naphthyl ring C atoms and the O atom, and the phenyl ring C atoms and the benzyl α-C atom, of 0.0176 (1) and 0.0024 (13) Å ...

Distributions of Polychlorinated Naphthalenes in Sediments of the Yangtze River, China
Molecules, 2021 The pollution status of polychlorinated naphthalenes (PCNs) in the sediment of the Yangtze River Basin, Asia’s largest river basin, was estimated. The total concentrations of PCNs (mono- to octa-CNs) ranged from 0.103 to 1.631 ng/g.

Isolation and Ionization of 1,1-Dihalogeno-1H-cyclopropa[a]-naphthalene
CHIMIA, 1985 1,1-Difluoro- and 1,1-dichloro-1H-cyclopropa[a]naphthalenes (1a and 1b) are prepared via dehydrohalogenation of the appropriate brominated carbene adducts (2a and 2b, respectively) of 4-bromo-1,2-dihydronaphthalene.
