A 1,5-Bifunctional Organomagnesium Reagent for the Synthesis of Disubstituted Anthracenes and Anthrones

Synthesis, 2017
The preparation of a 1,5-bifunctional organomagnesium alkoxide reagent by a deprotonation–magnesiation sequence is described. This reagent reacts with carboxylic acid esters to incorporate the carboxyl carbon atom of the ester into the newly formed ring.

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
