General Description

2-Amino-4-fluorobiphenyl, also known as 4-fluoro-2-aminobiphenyl, is a chemical compound with the molecular formula C12H10FN. It is an aromatic amine and a member of the biphenyl class of compounds, containing two benzene rings linked by a single bond. This chemical is used as an intermediate in the production of dyes, pigments, and pharmaceuticals. The fluorine atom in its structure makes it useful in organic synthesis and as a building block for pharmaceutical intermediates. It is also a known mutagen and potential carcinogen, posing health and safety risks to those who handle and work with it. Strict safety measures must be followed when handling 2-Amino-4-fluorobiphenyl to minimize exposure and prevent adverse health effects.

Synthesis of Fluorescent 4-Azapyrenes by Palladium(II)-Catalyzed Dual C?H Bond Activation and Annulation

Unique dual-emissive and deep-blue/green fluorescent multi-substituted 4-azapyrenes with bathochromic shift emission, quantum yields up to 0.60 and long excited-state lifetime were synthesized successfully by annulative π-extension reactions. This synthesis constitutes a palladium-catalyzed dehydrogenative annulation of N-acyl-2-aminobiaryls with in situ 1,3-diynes as a key step, giving substituted phenanthrenes via a rollover C?H bond activation, followed by Bischler-Napieralski cyclization. Further π-extension by superacid-mediated cyclization produced a blue fluorescent naphtho 4-azapyrene. (Figure presented.).

Photocatalytic xanthate-based radical addition/cyclization reaction sequence toward 2-biphenyl isocyanides: Synthesis of 6-alkylated phenanthridines

A photocatalytic xanthate-based radical addition/cyclization reaction cascade toward 2-biphenylisocyanides is described as a practical and modular approach to 6-alkylated phenanthridines. The use of xanthates as radical precursors allowed the synthesis of diversely 6-substituted phenanthridines. Electrophilic radicals derived from nitriles, aromatic and aliphatic ketones, malonates, and amide derivatives, as well as radicals derived from phthalimidomethyl and benzylic derivatives were successfully introduced. The reaction proceeds under mild conditions without a stoichiometric amount of oxidant. Thirty novel phenanthridine scaffolds were synthesized with yields ranging from 24 to 76%.

NBE-Controlled Palladium-Catalyzed Interannular Selective C-H Silylation: Access to Divergent Silicon-Containing 1,1′-Biaryl-2-Acetamides

A novel palladium-catalyzed interannular selective C-H silylation of 1,1′-biaryl-2-acetamides is described. The combination of palladium catalyst with copper oxidant enables meta- or ortho-selective C-H silylation by employing hexamethyldisilane as a trimethylsilyl source, which relies on the control of NBE derivatives as a switch, thus providing straightforward access to divergent silicon-containing 1,1′-biaryl-2-acetamides.
