Molecular recognition-based catalysis in nucleophilic aromatic substitution: A mechanistic study
Basilio, Nuno,Garcia-Rio, Luis,Pena-Gallego, Angeles,Perez-Lorenzo, Moises
, p. 1519 - 1526 (2012)
Nucleophilic aromatic substitution for nitro-activated substrates in the presence of glymes and crown ethers is reported. The kinetic study reveals the many-sided nature of the polyether-catalyzed SNAr mechanism as well as the main features aff
Characterization of solvent mixtures. Part 8 - Preferential solvation of chemical probes in binary solvent systems of a polar aprotic hydrogen-bond acceptor solvent with acetonitrile or nitromethane. Solvent effects on aromatic nucleophilic substitution r

, p. 207 - 220 (1999)
The use of chemical probes for the characterization of chemical properties was explored for completely non-aqueous aprotic binary solvent mixtures. The Dimroth-Reichardt ET(30) betaine dye, 4-nitrophenol, 4-nitroanisole, 4-nitroaniline and N,N-
Catalysis in Micellar Media. Kinetics and Mechanism for the Reaction of 1-Fluoro-2,4-dinitrobenzene with n-Butylamine and Piperidine in n-Hexane and AOT/n-Hexane/Water Reverse Micelles
Correa, N. Mariano,Durantini, Edgardo N.,Silber, Juana J.
, p. 5757 - 5763 (1999)
The nucleophilic aromatic substitution SNAr reaction of 1-fluoro-2,4-dinitrobenzene with n-butylamine and piperidine was studied in n-hexane and AOT/n-hexane/water reverse micelle media. The kinetic profile of the reactions was investigated as
Direct formation of aromatic C-N bonds. Regioselective amination of m- dinitrobenzene via fluoride promoted nucleophilic aromatic photosubstitution for hydrogen
Huertas, Inma,Gallardo, Iluminada,Marquet, Jordi
, p. 279 - 281 (2000)
Useful yields are achieved in the regioselective direct formation of anilines and aromatic amides through hydrogen nucleophilic aromatic photosubstitution of m-dinitrobenzene with primary amines and amides, promoted by fluoride anion.
Solvent effects on chemical processes: New solvents designed on the basis of the molecular-microscopic properties of (molecular solvent + 1,3-dialkylimidazolium) binary mixtures
Mancini,Fortunato,Adam,Vottero
, p. 87 - 95 (2008)
The purpose of this work was to analyze the microscopic feature of binary solvent systems formed by a molecular solvent (acetonitrile or dimethylformamide or methanol) and an ionic liquid (IL) cosolvent [1-(1-butyl)-3- methylimidazolium tetrafluoroborate
Photoacoustic Spectroscopy of Chemically Bonded Chromatographic Stationary Phases
Lochmueller, C. H.,Marshall, S. F.,Wilder, D. R.
, p. 19 - 23 (1980)
A qualitative study of chemically-bonded, chromatographic stationary phases was undertaken to assess the applicability of photoacoustic spectroscopy (PAS) to the characterization of chemically-modified surfaces.The ability of this technique to identify co
Mechanism of base catalysis in the reactions of phenyl aryl ethers with aliphatic amines in dimethyl sulfoxide
Chamberlin, Rachel A.,Crampton, Michael R.
, p. 1831 - 1838 (1995)
The reactions of n-butylamine, pyrrolidine and piperidine with phenyl 2,4,6-trinitrophenyl ether, 3, in DMSO result in the rapid reversible formation of adducts by reaction at the 3-position followed by attack at the 1-position leading to substitution of
Aryl-Diadamantyl Phosphine Ligands in Palladium-Catalyzed Cross-Coupling Reactions: Synthesis, Structural Analysis, and Application

Synthesis, temperature-dependent NMR structure investigation and utilization of a new, stable and easily accessible aryl-diadamantylphosphine ligand family is reported. The bulky and electron-rich phosphorus center of the ligand enhances the catalytic activity of palladium in cross-coupling reactions of sterically demanding ortho-substituted aryl halides. In our study, we demonstrated the synthetic applicability of the new phosphine ligands in Buchwald-Hartwig and tosyl hydrazone coupling reactions.
Pd(OAc)2-catalyzed dinitration reaction of aromatic amines
Feng, Yi-Si,Mao, Long,Bu, Xiao-Song,Dai, Jian-Jun,Xu, Hua-Jian
, p. 3827 - 3832 (2015/06/02)
Taking advantage of Pd(OAc)2-catalyzed dinitration reactions with Bi(NO3)3·5H2O in trifluoroethanol (TFE) and trifluoroacetic acid (TFA), we have developed an efficient and practical method for the synthesis of secondary dinitro-aromatic amines. The products could be applied to the preparation of 5-amine-N-methyl-benzimidazolone, the azo-dyes, economic advantages. The method has also been expanded to the dinitration reaction of some tertiary aromatic amines.
