10-Anthraquinone, 9,10-Anthracenedione

Diels-Alder Reaction. In 1928, Diels and Alder discovered that 1,3-unsaturated organic compounds reacted with quinoid systems to give partially hydrogenated, cycHc compounds. In the course of their work, they found that 1 mol of 1,4-naphthoquinone [130-15-4] reacted readily with 1 mol of 1,3-butadiene [106-99-0] to give a partially hydrogenated anthraquinone (11) l,4,4a,9a-tetrahydro-9,10-anthracenedione [56136-14-2] which, on oxidation with chromic oxide, produced anthraquinone (43) ...

Of the various anthracenedione isomers, only the 9,10-compound is used for the synthesis of dyes it is usually referred to simply as anthraquinone (6.1). The parent compound is pale yellow in colour, having a weak absorption band in the visible region (n—>tt transition). The presence of one or more electron-donating substituents leads to significant bathochromic effects so that relatively simple derivatives are of commercial importance as dyes. The colour of such compounds, which usually contain amino or hydroxy groups, can be attributed to the existence of a charge-transfer absorption band [1]. [Pg.280]

The mouse skin-painting bioassay results with 2,5-cyclo-hexadiene-l,4-dione (p-benzoquinone) were subsequently confirmed by Tiedemann (3916a). Neither of the higher molecular weight tricyclic quinones 9,10-anthracenedione (9,10-anthraquinone) (3865a) or 9,10-phenanthrenedione (9, 10-phenanthrenequinone) (3865a) was reported to be tumorigenic to mouse skin.

The oxidation-reduction potential of the aromatic hydrocarbon-quinone system and its possible involvement in cigarette smoke was revisited some years later. Schmeltz et aL (3510) reported that cigarette smoke condensate (CSC) possessed reducingpropertiessufflcienttoreduce2,5-cyclohexadiene-l,4-dione (1,4-benzoquinone p-benzoquinone) to 1,4-benzenediol (hydroquinone). This CSC-induced reduction apparently did not occur with 9,10-anthracenedione (9,10-anthraquinone). [Pg.548]
