Thermal generation and (inter)conversion of (multi) cyclopenta-fused polycyclic aromatic hydrocarbons

چکیده
FVT of I , 1 -dichloroand/or 1 -chloroethenyl substituted PAHs gives access to the CP-PAH's pyracylene (l), cyclopenta[cd]pyrene (12) and benz[ghi]fluoranthene (13), cyclopent[hi]aceanthrylene (18) and cyclopent[hi]acephenanthrylene (19), and the novel cyclopenta[cd]fluoranthene (22) and isomeric cyclopent[fg](25a), cyclopent[ik](25b) and cyclopent[rnn]acepyrylene (25c), respectively. The propensity of CP-PAHs to interconvert under high temperature FVT conditions is illustrated. Possible mechanisms, such as ring-contractionhing-expansion via 1,2-H and 1,2-C shifts, are discussed.

Comparative tumorigenicity of the cyclopenta-fused polycyclic aromatic hydrocarbons aceanthrylene, dihydroaceanthrylene and acephenanthrylene in preweanling CD-1 and BLU:Ha mouse bioassays.
Cyclopenta-fused polycyclic aromatic hydrocarbons are ubiquitous environmental pollutants and potential human health biohazards. In this study, the tumorigenicity of three single cyclopenta-fused polycyclic aromatic hydrocarbons, aceanthrylene, dihydroaceanthrylene and acephenanthrylene, was examined in preweanling CD-1 and BLU:Ha mouse bioassays at total doses of 175, 437.5 and 875 micrograms/...
متن کاملBacterial and human cell mutagenicity study of some C18H10 cyclopenta-fused polycyclic aromatic hydrocarbons associated with fossil fuels combustion.
A number of isomeric C18H10 polycyclic aromatic hydrocarbons (PAHs), thought to be primarily cyclopenta-fused PAHs, are produced during the combustion and pyrolysis of fossil fuels. To determine the importance of their contributions to the total mutagenic activity of combustion and pyrolysis samples in which they are found, we characterized reference quantities of four C18H10 CP-PAHs: benzo[ghi...
متن کاملChemical characterization and bioactivity of polycyclic aromatic hydrocarbons from non-oxidative thermal treatment of pyrene-contaminated soil at 250-1,000 degrees C.
In this paper we report yields, identities, and mutagenicities of products from heating a polycyclic aromatic hydrocarbon (PAH)-contaminated, Superfund-related synthetic soil matrix without exogenous oxygen. We heated batch samples of soil pretreated with 5.08 wt% (by weight) pyrene in a tubular furnace under a constant flow of helium gas at 250, 500, 750, and 1,000 +/- 20 degrees C. Dichlorome...
متن کاملMutagenesis and morphological transformation of mammalian cells by a non-bay-region polycyclic cyclopenta(cd)pyrene and its 3,4-oxide.
Cyclopenta(cd)pyrene, a constituent of environmental emissions, has been found to mutate and transform mammalian cells in culture. Cyclopenta(cd)pyrene 3,4-oxide, a presumed metabolite, was found to be a direct-acting mutagen and to transform mammalian cells. These results suggest that cyclopenta(cd)pyrene 3,4-oxide may be an ultimate mutagenic form of the parent hydrocarbon.
