Anodic Coupling of Diphenylbenzo[k]fluoranthene: Mechanistic and Kinetic Studies Utilizing Cyclic Voltammetry and Electrogenerated Chemiluminescence.
Upon oxidation at a platinum electrode, (7,12-diphenyl)benzo[k]fluoranthene (1) undergoes intermolecular dehydrogenative coupling to form bis-4,4'-(7,12-diphenyl)benzo[k]fluoranthene (2). Further oxidation of this product results in a much slower intramolecular coupling reaction that yields dibenzo{[f,f']-4,4',7,7'-tetraphenyl}diindeno[1,2,3-cd:1',2',3'-lm]perylene (3). 2 can be synthesized via...

متن کاملDimethyl sulfoxide, a convenient solvent of 7,12-dimethylbenz(a)anthracene for intravenous injection.
SUMMARY Dimethyl sulfoxide is a convenient solvent of 7,12-dimethylbenz(a)anthracene and related polycycic aromatic hydrocarbons for i.v. injection. As judged by its ability to induce both adrenal necrosis and mammary tumors, this solu tion is at least as active as fatty emulsions of 7,12-dimethyl benz(a)anthracene now in general use. While the preparation of emulsions is timeconsuming andrequi...
متن کاملPotent tumor-initiating activity of the 3,4-dihydrodiol of 7,12-dimethylbenz(a)anthracene in mouse skin.
The abilities of the racemic trans-3,4-, 5,6-, and 8,9-dihydrodiols of 7,12-dimethylbenz(a)anthracene to initiate skin tumors in mice were determined by using a two-stage system of tumorigenesis. The 7,12-dimethylbenz(a)anthracene trans-3,4-dihydrodiol was found to be much more active as a tumor initiator than the parent hydrocarbon. The 7,12-dimethylbenz(a)anthracene trans-5,6- and 8,9-dihydro...
متن کاملThe current use of studies on promoters and cocarcinogens in quantitative risk assessment.
Several of the priority pollutants discussed in EPA's Ambient Water Quality Criteria documents have been reported to have promotion or cocarcinogenic activity. For example, phenol appears to have tumor-promoting activity in mice when repeatedly applied after initiation with either 7,12-dimethyl-1,2-benzanthracene (DMBA) or benzo(a)pyrene (BaP). Similarly, it has been reported that 2,3,7,8-tetra...
