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.

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.

Thermoelectroluminescence in Anthracene and Anthracene Doped With Acridine Phosphors

Macromolecular Symposia
AbstractIn the present study, an effort is made to record the thermoelectroluminescence (TEL) glow curves and electroluminescence (EL) spectra for anthracene, acridine, and anthracene doped with acridine to determine the trap depth and escape frequency in these materials.

Synthesis of New Anthracene Derivatives

The Journal of Organic Chemistry, 2006
An efficient synthesis is described for hexabromoanthracenes 3 and 4 by direct bromination of 9,10-dibromoanthrecene 2. Whereas base-induced elimination of hexabromide 3 with t-BuOK gave 2,3,9,10-tetrabromoanthracene 5, the reaction of hexabromide 4 with DBU afforded 1,3,9,10-tetrabromoanthracene 6 as the sole product.

Radiation Induced Paramagnetic Centers in Anthracene and Deuterated Anthracene

Molecular Crystals, 1968
Abstract EPR Studies of radiation damage in anthracene C14H10 and deuterated anthracene (C14D10) powders have been made up to a dose of 7 × 108 rad. Interpretation of the spectra is consistent with that resulting from the hyperfine interaction of three equivalent protons. Excessive breadth of the spectrum of the radical produced in C14D10 is attributed

Anthracene and Anthracene-Tetracene Crystals from Vapor

Molecular Crystals, 1968
Abstract Molecular crystals in general are receiving increased attention and anthracene crystals in particular are in demand for use in various studies. Consequently, several techniques have been developed for growing anthracene crystals–most of which have involved growth from the melt.1–3 In those common method is to use a cooled collector plate.3,4 ...
