Action of stilbene on tetrachloro-ο-benzoquinone was written by Schonberg, Alexander;Latif, Nazih. And the article was included in Journal of the American Chemical Society in 1950.COA of Formula: C8H13N This article mentions the following:
Tetrachloro-ο-quinone (I) (1 g.) and (PhCH:)2 (II) in 30 cc. C6H6, exposed 13 days to sunlight, give 2,3-diphenyl-5,6,7,8-tetrachloro-1,4-benzodioxan (III), m. about 172°; III results in 70% yield on boiling 1.2 g. I and 0.9 g. II in C6H6 15 hrs. in the dark. I (0.6 g.) and 0.5 g. (p-MeC6H4CH:)2, exposed 10 days to sunlight, give 2-phenyl-3-(p-tolyl)-5,6,7,8-tetrachloro-1,4-benzodioxan, m. 132°. III, heated 15 min. in a C6H4(CO2Et)2 bath (oil-pump vacuum), gives II. III does not react with ο-C6H4(NH2)2 (refluxed 2 hrs. in 90% AcOH). In the experiment, the researchers used many compounds, for example, 2-Cyclohexylacetonitrile (cas: 4435-14-7COA of Formula: C8H13N).
2-Cyclohexylacetonitrile (cas: 4435-14-7) belongs to nitriles. Trimerization of aromatic nitriles requires harsh reaction conditions, high temperatures, long reaction times, and pressure. Nitrile groups in organic compounds can undergo a variety of reactions depending on the reactants or conditions. A nitrile group can be hydrolyzed, reduced, or ejected from a molecule as a cyanide ion.COA of Formula: C8H13N
