The C-N bond formation is one of the fundamental reactions in organic chemistry, because of the widespread presence of amine moieties in pharmaceuticals and biologically active compounds. Palladium-catalyzed C-N coupling of haloarenes represents one of the most efficient approaches to aromatic amines. Nitroarenes are ideal alternative electrophilic coupling partners, since they are inexpensive and readily available. The denitration and cross-coupling using nitroarenes as the electrophilic partners is challenging, because of the low reactivity of the Ar-NO2 bond toward oxidative addition. We report here the C-N coupling of nitroarenes and amines using palladium/5-(2,4,6-triisopropylphenyl)imidazolylidene[1,5-a]pyridines as the catalyst. The ligands are readily available from commercial chemicals. The reaction shows broad substrate scope and functional group tolerance. The method is applicable to both aromatic and aliphatic amines, and many secondary and tertiary aromatic amines bearing various functional groups were obtained in high yields.

Palladium-catalyzed amination of aryl sulfides with anilines

supporting information, p. 9329 - 9333,5 (2014/11/07)
A combination of a palladium-NHC catalyst and potassium hexamethyldisilazide enables the amination of aryl sulfides with anilines to afford a wide variety of diarylamines. The reaction conditions are versatile enough for the reaction of even bulky ortho-substituted aryl sulfides. This amination can be applied to the modular synthesis of N-aryl carbazoles from the corresponding ortho-bromothioanisoles. As aryl sulfoxides undergo extended Pummerer reactions to afford ortho-substituted aryl sulfides, the Pummerer products are thus useful substrates for the amination to culminate in efficient syntheses of a 2-anilinobenzothiophene and an indole as proof-of-principle of the utility of the extended Pummerer reaction/amination cascade. Switching S to N: Transformation of inert C-S bonds of aryl sulfides into C-N bonds is achieved using a palladium complex with an N-heterocyclic carbene ligand. Thanks to the efficient conditions for amination of bulky sulfides, the synthesis of carbazole products from 2-biphenylylamine is achieved through oxidative C-N bond formation. When combined with extended Pummerer reactions, intriguing nitrogen-containing molecules are prepared.
THE REACTION OF ORTHO-SUBSTITUTED AROMATIC AZIDES WITH BORON TRICHLORIDE OR TRIFLUORIDE

The reactiont of boron trichloride or trifluoride with ortho-aryl, -diazoaryl, and -arylazoaryl phenyl azides in benzene at room temperature generally gives fused azoles in high yields.Treatment of 2-nitrophenyl azide with boron trichloride mainly affords chlorinated nitroanilines, whereas with boron trifluoride it gives N-o-nitrophenylaniline.In aromatic solvents at 60 deg C in the presence of boron trifluoride-diethyl ether, 2-azidobiphenyl forms carbazole and 2-(arylamino)biphenyls, the formation of which depends greatly upon the nucleophilicity of the solvent used; however, its pseudo-first-order decomposition rate is slightly greater in benzene than in toluene or m-xylene.Under the same conditions, phenyl azide forms diarylamines.The results suggest that singlet nitrenium ions, arising from the corresponding azidetrihalogenoborane complexes by loss of molecular nitrogen, are generally the reactive intermediates.
