Diels-alder reaction of isobenzofurans/cyclopentadienones with tetrathiafulvalene: Preparation of naphthalene, fluoranthene, and fluorenone derivatives

Diels-Alder reaction of 1,3-diarylbenzo[c]furan/cyclopentadienone with TTF followed by triflic acid mediated cleavage of the resulting adducts led to the formation of the respective 1,4-diaryl substituted naphthalenes, fluoranthenes, and fluorenones. The photophysical properties of representative diaryl-substituted hydrocarbons are also reported.

Chemoselective Ruthenium-Catalyzed C-O Bond Activation: Orthogonality of Nickel- and Palladium-Catalyzed Reactions for the Synthesis of Polyaryl Fluorenones

Ruthenium-catalyzed C-O bond activation/arylation of methoxy and O -carbamoyl-substituted fluorenones is reported. Established are new reactions of compound 1 (X = H) to aryl (2) and 1,8-diaryl (3) fluorenones. Orthogonal ruthenium-, palladium- and nickel

Regioselective Suzuki-Miyaura Cross-Coupling Reactions of the Bis(triflate) of 1,4-Dihydroxy-9 H -fluoren-9-one

1,4-Diaryl-9H-fluoren-9-ones were prepared by regioselective Suzuki-Miyaura cross-coupling reaction of the bis(triflate) of 1,4-dihydroxy-9H-fluoren-9-one. The reactions proceeded with excellent site selectivity. The first attack occurs at position 1, due to electronic reasons.

Polycyclic Aromatic Compounds: Part III-Synthesis of 1,3-Diaryl-2,8-dihydro-2,8-dioxocyclopentadienes and Their Conversion into Fluorenone and Fluorene Derivatives

1,3-Diaryl-2,8-dihydro-2,8-dioxocyclopentadienes (IV) have been prepared from ninhydrin hydrate (I) and 4,4'-disubstituted dibenzyl ketones (II).During the formation of (IV), a side product has also been isolated, and assigned structure (V) based on chemical and spectral evidences.The dienones (IV) readily undergo cycloaddition reaction with ethylenic and acetylenic compounds forming fluorenone derivatives which on subsequent reduction afford fluorenones.
