A new straightforward synthetic strategy has been elaborated to achieve star-shaped triazatrinaphthylene and, for the first time, triazatrianthrylene derivatives. Their solution- and solid-state properties were thoroughly characterized by cyclic voltammetry, UV–vis absorption spectroscopy, X-ray diffraction, and density functional theory calculations. Original hexagonal molecular arrangements were found in the crystal phase, which opens a new pathway for designing materials with improved three-dimensional charge-transport properties.
Pd-Catalyzed Approach for Assembling 9-Arylacridines via a Cascade Tandem Reaction of 2-(Arylamino)benzonitrile with Arylboronic Acids in Water
Ye, Xuanzeng,Xu, Beihang,Sun, Jiani,Dai, Ling,Shao, Yinlin,Zhang, Yetong,Chen, Jiuxi

A novel palladium-catalyzed protocol for the synthesis of 9-arylacridines via tandem reaction of 2-(arylamino)benzonitrile with arylboronic acids in water has been developed with good functional group tolerance. The present synthetic route could be readily scaled up to gram quantity without difficulty. This methodology was further extended to the synthesis of a 4′-OH derivative, which showed estrogenic biological activity. Preliminary mechanistic experiments showed that this transformation involves a nucleophilic addition of aryl palladium species to the nitrile to generate an aryl ketone intermediate followed by an intramolecular Friedel-Crafts acylation and dehydration to acridines.

Palladium-catalyzed oxidative C-H bond acylation of N-nitrosoanilines with toluene derivatives: A traceless approach to synthesize N-alkyl-2-aminobenzophenones
Wu, Yinuo,Feng, Ling-Jun,Lu, Xiao,Kwong, Fuk Yee,Luo, Hai-Bin
, p. 15352 - 15354 (2015/01/08)
A palladium-catalyzed cascade cross-coupling of N-nitroso-anilines and toluene derivatives for the direct synthesis of N-alkyl-2-aminobenzophenones is described. N-nitroso groups in anilines can act as the traceless directing groups while toluene derivatives can serve as effective acyl precursors under mild reaction conditions.
Continuous-flow synthesis of trimethylsilylphenyl perfluorosulfonate benzyne precursors
Michel, Boris,Greaney, Michael F.
supporting information, p. 2684 - 2687 (2014/06/09)
2-(Trimethylsilyl)phenyl perfluorosulfonated aryne precursors may now be accessed using flow chemistry, enabling the fast preparation of pure compounds with no requirement for low temperature lithiation or column chromatography. The process has been adapted to novel nonaflate precursors, utilizing the cheaper and more user-friendly nonaflyl fluoride reagent. The resultant nonaflates are shown to successfully participate in a range of aryne reaction classes.

experimental part, p. 8450 - 8456 (2012/10/07)
Vinylogy is a widely accepted principle involving the transfer of electronic chemical character through a double bond, and many reactions have been developed by applying this concept. In contrast, phenylogy, which involves the connection of two substituen
Insertion of benzene rings into the amide bond: one-step synthesis of acridines and acridones from aryl amides
Pintori, Didier G.,Greaney, Michael F.

"Chemical Equation Presented" Insertion of benzene rings into the amide bond using the reactive intermediate benzyne is described. Aromatic amides undergo smooth insertion when treated with O-triflatophenyl silane benzyne precursors, producing versatile a
Gas-phase cyclisation reactions of 1-(2-arylaminophenyl)alkaniminyl radicals
Leardini, Rino,McNab, Hamish,Nanni, Daniele,Parsons, Simon,Reed, David,Tenan, Anton G.
, p. 1833 - 1838 (2007/10/03)
Flash vacuum pyrolysis (FVP) of the oxime ethers 9-11 at 650°C (10-2-10-3 Torr) gives products such as the nitrile 17, carbazoles 19 and 20 and acridines 18 and 21 derived from the corresponding iminyl radicals 13-15. The mechanism proposed for the formation of the acridines involves a key hydrogen abstraction by the iminyl of the adjacent N-H atom. When this route is blocked by an N-methyl group, as in 12, alternative cyclisations ensue, yielding the dihydroquinazoline 26 (via another hydrogen abstraction process) and the benzimidazole 25 (via an iminyl-imidoyl interconversion).
