[source] Well-Defined Regioselective Iminopyridine Rhodium Catalysts for Anti-Markovnikov Addition of Aromatic Primary Amines to 1-OctyneADVANCED SYNTHESIS & CATALYSIS (PREVIOUSLY: JOURNAL FUER PRAKTISCHE CHEMIE), Issue 6 2009Carlos Alonso-Moreno Abstract A series of cationic rhodium(I) complexes of the type [Rh(N-N)(COD)][BPh4], containing the following iminopyridine-based bidentate nitrogen donor ligands (N-N): 2,6-diisopropyl- N -[1-(pyridin-2-yl)ethylidene]aniline (dipea, 1), 2,6-dimethyl- N -[1-(pyridin-2-yl)ethylidene]aniline (dmpea, 2), 2,4,6-trimethyl- N -[1-(pyridin-2-yl)ethylidene]aniline (tmpea, 3) and 2,6-diisopropyl- N -[1-(4-methylpyridin-2-yl)ethylidene]aniline] (dipmpea, 4), were synthesized and fully characterized. The intermolecular hydroamination of a terminal alkyne, such as 1-octyne, with primary aromatic amines in the presence of these cationic rhodium(I) catalysts occurred in an anti-Markovnikov fashion. The rhodium complexes catalyzed the regioselective formation of the E- isomer of the corresponding imine, without the formation of the Z -isomer or the Markovnikov product. These compounds are also presented as efficient regioselective catalysts for the hydroamination of anilines in the presence of air and/or water. [source] Hemilabile-coordinated copper promoted amination of aryl halides with ammonia in aqueous ethylene glycol under atmosphere pressureAPPLIED ORGANOMETALLIC CHEMISTRY, Issue 4 2009Zhennü Guo Abstract Direct amination of aryl iodides and bromides with ammonia under 1 atm pressure has been effected using in situ -generated hemilabile coordinated copper(I) species from copper(I) halides or copper metal in aqueous ethylene glycol, producing primary aromatic amines in good yields. Ammonia pressure and water were found to accelerate the copper-mediated reaction while strong chelating ligands showed a suppression effect. A rationale for the copper-mediated amination of aryl halides with ammonia is given based on a double-face role of chelating effect. Copyright © 2009 John Wiley & Sons, Ltd. [source] |
