Mono- and Dinitro-BN-Naphthalenes: Formation and Characterization
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 ...

In aquatic systems, sediment is both a sink for persistent organic pollutants (POPs) and a potential source of POPs release. Consequently, it is important to understand the pollution characteristics and sources of polychlorinated naphthalenes (PCNs) as ...

In this paper, we report an intramolecular cyclization of benzylic-substituted propargyl alcohols promoted by iron(III) chloride and diorganyl diselenides to give 2-organoselenyl-naphthalenes via a sequential carbon–carbon/carbon–selenium bond formation.

Synthesis of Substituted Naphthalenes via a Catalytic Ring-Expansion Rearrangement
A new methodology for the preparation of substituted naphthalenes starting from readily available indenones, organometal reagents, and trimethylsilyldiazomethane via a catalytic rearrangement process is described.

Distributions of Polychlorinated Naphthalenes in Sediments of the Yangtze River, China
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
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.
