WebJan 28, 2024 · The benzylic hydrogens of alkyl substituents on a benzene ring are activated toward free radical attack, as noted earlier. Furthermore, S N 1 S N 2 and E1 reactions of benzylic halides, show enhanced reactivity, due to the adjacent aromatic ring. The possibility that these observations reflect a general benzylic activation is supported by the ...

WebNov 18, 2024 · According to [literature] [1] it is actually anti-aromatic. I guess it depends on when you call something like that aromatic or not. Is the system fully delocalized, are all bonds equal or close in bond lenghts, is there considerable out of plane twisting from the planarity, does the aromatic ring current extend through the whole molecule, ...? http://www.t3db.ca/toxins/T3D0625 Fluorene can be found after the incomplete combustion of plastics such as PS, PE and PVC. Acidity. The C9-H sites of the fluorene ring are weakly acidic (pK a = 22.6 in DMSO.) Deprotonation gives the stable fluorenyl anion, nominally C 13 H 9 −, which is aromatic and has an intense orange colour.
