Anthracene is a solid polycyclic aromatic hydrocarbon (PAH) of formula C 14 H 10, ... Chemical oxidation occurs readily, giving anthraquinone, C 14 H 8 O 2 (below), ...
The oxidation of anthracene. Chromium(VI) is the typical oxidant. The Friedel-Crafts reaction of benzene and phthalic anhydride in presence of AlCl 3. o-Benzoylbenzoic acid is an intermediate. This reaction is useful for producing substituted anthraquinones. The Diels-Alder reaction of naphthoquinone and butadiene followed by oxidative ...
The reaction is named after its inventor, the German chemist Karl Elbs, also responsible for the Elbs oxidation. The reaction was published in 1884. The reaction was published in 1884. [ 1 ] [ 2 ] [ 3 ] Elbs however did not correctly interpret the reaction product due to a lack of knowledge about naphthalene structure.
9,10-Dihydroanthracene is an organic compound that is derived from the polycyclic aromatic hydrocarbon anthracene. Several isomers of dihydroanthracene are known, but the 9,10 derivative is most common. It is a colourless solid that is used as a carrier of H 2 as a hydrogen-donor. [2]
The reaction of anthracene with N-methylformanilide, also using phosphorus oxychloride, gives 9-anthracenecarboxaldehyde: N -Methylformanilide and anthracene and phosphorus oxychloride In general, the electron-rich arene ( 3 ) must be much more active than benzene for the reaction to proceed; phenols or anilines are good substrates.
The earliest example of a [4+4] photocycloaddition was the photodimerization of anthracene, discovered in 1936. [1] This reaction has remained one of the most reliable photocycloadditions and is the basis of continuing investigation.
The name "anthraquinone" was first used by German chemists Carl Graebe and Carl Theodore Liebermann in a 1868 publication describing the chemical synthesis of the red dye alizarin from anthracene, a component of coal tar. This discovery led to the industrial production of alizarin and the impetus for further research on anthraquinone chemistry. [1]
The anthraquinone process, also called the Riedl–Pfleiderer process, is a process for the production of hydrogen peroxide, which was developed by IG Farben in the 1940s., [1] The industrial production of hydrogen peroxide is based on the reduction of oxygen, as in the direct synthesis from the elements.
