Atmospheric polychlorinated naphthalenes in Ghana.
Environmental Science and Technology, 2012A nationwide monitoring of atmospheric POPs (persistent organic pollutants) was conducted in Ghana between May and July 2010, applying polyurethane foam (PUF) disk passive air samplers (PAS).

1,1-Carboboration route to substituted naphthalenes.
Organic Letters, 20121,2-Bis(alkynyl)benzene derivatives react with strongly electrophilic boranes to yield in boryl-functionalized bulky naphthalene derivatives by means of a sequence of 1,1-carboboration reactions. These substrates can be functionalized by transition metal

THE BACTERIAL DISSIMILATION OF NAPHTHALENE
Canadian Journal of Microbiology, 1955Data are presented indicating that the major pathway for the oxidation of naphthalene by a strain of Pseudomonas occurs via salicylic acid, which is further oxidized through catechol to β-ketoadipic acid. On the basis of growth, simultaneous adaptation, and cell-free extract experiments, the following compounds are regarded as unlikely intermediates in

Depending on the ratio of the substrates and the reaction conditions, the Cu(I)-catalyzed domino reaction between bromobenzyl bromides and β-ketoesters exclusively yields either 4H-chromenes or naphthalenes.

Formation of bound residues by naphthalene and cis-naphthalene-1,2-dihydrodiol
Chemosphere, 2004The formation of bound residues by naphthalene and its metabolite, cis-naphthalene-1,2-dihydrodiol, in a sediment (1% OC), a silty loam soil (2.9% OC) and a peat (26% OC) was examined. The experiments were carried out under both sterile and nonsterile conditions for up to 35 days.

Au(I)-catalyzed cyclization of alkenyl carbonyl compounds leading to a variety of substituted naphthalenes has been developed. This process exploits a dual function of the Au(I) catalyst: (1) the oxophilic nature of the Au(I) catalyst, counterintuitive ...

Heteroatom as a promotor: synthesis of polyfunctionalized benzenes and naphthalenes.
Journal of Organic Chemistry, 2011Construction of a new benzene via the electrocyclization of diene-allene is an efficient protocol to access polysubstituted benzenes from simple, readily available starting materials.

Degradation of the Naphthalene
Research Journal of Pharmacy and Technology, 2017Naphthalene is one of the easy Polycyclic Aromatic Hydrocarbon (PAH). In the field of oil refineries and fossil fuels, the Polycyclic Aromatic Hydrocarbon is one of the main constraints and the contents are toxic and carcinogenic. In this work the bacterial strain was isolated and the isolates are determined by the biochemical measurements.
