The tumor-initiating activities of benzo[a]fluoranthene (BaF), benzo[b]fluoranthene (BbF), naphtho[1,2-b]fluoranthene (NbF) and naphtho[2,1-a]fluoranthene (NaF) were evaluated on the skin of female CD-1 mice. Each of these polycyclic aromatic hydrocarbons was assayed at total initiation doses of 1.0 and 4.0 mumol/mouse.

Fluoranthenes by cyclodehydrogenation. Benzo[a]naphtho[j]1,2-fluoranthene
Journal of the Chemical Society C: Organic, 1966The palladium–sulphur method has been used to dehydrogenate 3,4,5,6,7,8-hexahydro-1-(1,2,5,6,7,8-hexahydro-4-phenanthryl)anthracene to the title compound. Two intermediates, tetrahydrobenzo[a]-5,6,7,8-tetrahydronaphtho[1,2-j]fluoranthene and tetrahydrobenzo[a]naphtho[1,2-j]fluoranthene, were isolated and their structures established.

3-Acetamido- and 3-amino-nuoranthene are brominated in the 2-position. Two new fluoranthene compounds are reported: 2-bromo-3-acetamidofluoranthene and 2-bromofluoranthene. The theoretical implications of these results are discussed.

Abstract Analysis of the 60 Mc/sec proton magnetic resonance spectra of fluoranthene (I), benzo [ k ] fluoranthene (II), and benzo [ ghi ] fluoranthene (III) have been carried out and, for I and II, confirmed at 100 Mc/sec. Differential solvent shifts for the protons helped in the analysis of I and were also observed in III; their presence may imply ...

On the bioactivation and genotoxic action of fluoranthene
Archives of Toxicology, 1992Fluoranthene (FA) was studied with respect to possible mechanisms of its high mutagenicity but low carcinogenicity, in comparison with the corresponding properties of benzo[a]pyrene (BaP), and with regard to the synergism of these two compounds shown by van Duuren and Goldschmidt (J Natl Cancer Inst 56, 1976, 1237).

Fluoranthene is one of the predominant compounds found in soils and sediments contaminated with polycyclic aromatic hydrocarbons (PAH). Four bacterial strains isolated from PAH-contaminated soils transformed fluoranthene to a number of products during growth on phenanthrene, including the novel metabolites fluoranthene-2,3-dione (F23Q) and fluoranthene-

Studies in the fluoranthene series
20188. Oxidation of 11-benzoyl-fluoranthene with chromic anhydride in glacial acetic acid gave an acid which was different from that obtained in 7. Decarboxylation gave 2-benzoyl-fluorenone which proved that the benzoyl group was in the 11- position in the original benzoyl-fluoranthene.
