Web5 okt. 2024 · The (4n+2)π aromatic systems are studied in variants of C8H 8 ( n+2) (n = −6, −4, −2, 0) via the localized orbital localization (LOL) and the electron localized function (ELF) by considering the induced current density. In this work, a four-electron dia-tropic (aromatic) ring current for (4n+2)π variants of C8H 8 ( n+2) (n = −6, −4, −2, 0) and a two-electron … Unlike benzene, C 6 H 6, cyclooctatetraene, C 8 H 8, is not aromatic, although its dianion, C 8 H 2− 8 (cyclooctatetraenide), is. Its reactivity is characteristic of an ordinary polyene, i.e. it undergoes addition reactions. Benzene, by contrast, characteristically undergoes substitution reactions, not … Meer weergeven 1,3,5,7-Cyclooctatetraene (COT) is an unsaturated derivative of cyclooctane, with the formula C8H8. It is also known as [8]annulene. This polyunsaturated hydrocarbon is a colorless to light yellow flammable … Meer weergeven Richard Willstätter's original synthesis (4 consecutive elimination reactions on a cyclooctane framework) gives relatively low yields. … Meer weergeven The π bonds in COT react as usual for olefins, rather than as aromatic ring systems. Mono- and polyepoxides can be generated by reaction of COT with peroxy acids or with dimethyldioxirane. Various other addition reactions are also known. Furthermore, Meer weergeven 1,3,5,7-Cyclooctatetraene was initially synthesized by Richard Willstätter in Munich in 1905 using pseudopelletierine as the starting … Meer weergeven Early studies demonstrated that COT did not display the chemistry of an aromatic compound. Then, early electron diffraction experiments … Meer weergeven Cyclooctatetraene has been isolated from certain fungi. Meer weergeven COT readily reacts with potassium metal to form the salt K2COT, which contains the dianion C 8H 8. The dianion is planar, octagonal, and Meer weergeven
