TL;DR: Phenyliminodimagnesium reagent (PhN(MgBr)2) and its o- and p-methoxy derivatives were found to be effective for condensation with benzophenones and fluorenone as mentioned in this paper.
Abstract: Phenyliminodimagnesium reagent (PhN(MgBr)2) and its o- and p-methoxy derivatives, prepared in THF by treatment of anilines with EtMgBr, were found to be effective for condensation with benzophenones and fluorenone. The corresponding anils (N-(diarylmethylene)anilines) were prepared in good yields.

TL;DR: The photoinitiators are a mixture of an aromatic carbonyl compound A which is derived from benzophenone, fluorenone, anthraquinone, xanthene, thioxanthone or acridone as discussed by the authors.
Abstract: Photopolymerizable coating compositions contain, as the binder, olefinically unsaturated compounds having a boiling point above 50° C, together with from 0.5 to 15% by weight of photoinitiators, based on the binder. The photoinitiators are a mixture of an aromatic carbonyl compound A, which is a derivative of benzoin or benzil, which has at least one carbon-oxygen single bond in the α-position relative to the carbonyl group, an aromatic carbonyl compound B which is derived from benzophenone, fluorenone, anthraquinone, xanthene, thioxanthone or acridone, and an amine C of the general formula ##STR1## where R', R" and R"' are H, alkyl of 1 to 10 carbon atoms, cycloalkyl of 3 to 10 carbon atoms, aryl, hydroxyalkyl of 1 to 8 carbon atoms or alkoxyalkyl of 2 to 4 carbon atoms, but at most 2 substituents are H and at most 2 substituents are aromatic. These coating compositions may be used for finishing various substrates, as fillers or as printing inks.

TL;DR: A series of bromo-, nitro-, and bromonitrofluorenones were synthesized chemo-and regioselectively in 90-98% yield via electrophilic aromatic bromination and nitration under mild conditions using water as the sole solvent as mentioned in this paper.

TL;DR: In this article, a diphenylfluorenone-diboronic acid adduct was designed to create structurally rigid oligomers, resulting in the restriction of intramolecular rotations.
