Abstract
Iron-catalyzed quaternary peroxidation of 9-alkyl-9H-fluorenes involving a radical mechanism was effectively performed. Oxidation of 9H-fluorenes to 9-fluorenones and oxidative C![[double bond, length as m-dash]](https://www.rsc.org/images/entities/char_e001.gif)
C bond cleavage in 9-alkylidene-fluorenes were also performed.

Abstract
An efficient synthetic route to functionalized benzo[b]fluorenes and benza[a]anthracenes has been developed via triflic acid mediated tandem isomerization/cyclodehydration of formyl bearing 1-benzylidene-2,3-dihydroindene/1-benzylidene-tetrahydronaphthalene derivatives.

Abstract
Functionalized fluorenones/fluorenes are generally synthesized via cross-coupling reactions. Described here is the modification of the fluorene/fluorenone core via a C–H functionalization tactic and augmentation of the fluorenes/fluorenones library.

Abstract
Sterically hindered 2,7-diaryl fluorenes have been efficiently synthesized via double Suzuki–Miyaura cross-coupling reactions of challenging 2,7-dichlorofluorene with multiple di-ortho-substituted arylboronic acids using the NHC–Pd catalyst INPd.
