Bioalkylation of benz[a]anthracene, 7-methylbenz[a]anthracene, and 12-methylbenz[a]anthracene in rat lung cytosol preparations

Biochemical Pharmacology, 1991
Benz[a]anthracene (BA) and the monomethyl meso-anthracenic or L-region derivatives 7-methylbenz[a]anthracene (7-methylBA) and 12-methylbenz[a]anthracene (12-methylBA) underwent a bioalkylation substitution reaction in rat lung ctyosol preparations, fortified with S-adenosyl-L-methionine to form the more potent carcinogen 7,12-dimethylbenz[a]anthracene.

Photoionization of anthracene and anthracene derivatives

Journal of Photochemistry and Photobiology A: Chemistry, 1999
Anthracene (III) and the derivatives 9-methoxymethylanthracene (IV), 9-cyanoanthracene (V) and (E-3-phenyl-prop-2-ene-1-yl(anthracene-9-methyl)-ether) (I) were subjected to irradiation at inca347 nm in dilute deoxygenated acetonitrile solution at room temperature.

Photoactivatable Anthracenes

The Journal of Organic Chemistry, 2014
Fifteen substituted maleimide cycloadducts of anthracene derivatives were synthesized in one or two steps from available precursors in yields ranging from 32 to 63%. They differ in the nature of the group on the maleimide nitrogen atom and of the substituents on the anthracene platform.

The quenching of anthracene triplets by ground-state anthracene

Chemical Physics Letters, 1983
Abstract The first-order decay constant, k dt , of anthracene triplets, 3 A*, in benzene depends linearly on ground-state anthracene, 1 A, concentration: k dt = k dt o + k sq [ 1 A], where k dt o = 49 ± 12 s −1 and k sq = (3.19 ± 0.10) × 10 5 M −1 s −1 at 23°C.

Anthracene Carboxyimides and Their Dimers

Chemistry – A European Journal, 2008
AbstractSoluble anthracenedicarboxyimides have been prepared and undergo a photodimerisation of the anthracene skeleton, which is important for their application as antitumour agents, such as azonafides. Reaction under strongly alkaline conditions causes CC coupling to form soluble dimeric fluorescent dyes with bathochromic absorption and fluorescence

Anthracene 1,2-oxide: synthesis and role in the metabolism of anthracene by mammals

Journal of the Chemical Society, Perkin Transactions 1, 1979
Synthesis of anthracene 1,2-oxide proceeds in good yield via dehydrobromination of 1 -acetoxy-2,4-dibromo1,2,3,4-tetrahydroanthracene. In contrast, dehydrobromination of 2-acetoxy-3,4-dibromo-1,2,3,4-tetrahydroanthracene produced 1 -bromoanthracene instead of the desired anthracene 2,3-oxide or its oxepin tautomer.

The bromination of anthracene

Journal of Chemical Education, 1966
This reaction illustrates the property of anthracene of adding the halogen molecule and later losing the elements of HBr to form the monobrominated hydrocarbon.
