Chan, Jessica Z.,Chang, Yejin,Wasa, Masayuki
supporting information, p. 984 - 988 (2019/02/14)
An efficient method for the coupling of N-alkylamines with silicon enolates to generate β-amino carbonyl compounds is disclosed. These reactions proceed by activation of α-amino C-H bonds by B(C6F5)3, which likely generate

Efficient copper-catalyzed amination of DNA-conjugated aryl iodides under mild aqueous conditions
Ruff, Yves,Berst, Frédéric
supporting information, p. 1188 - 1193 (2018/08/01)
Herein, we describe the development of copper-catalyzed cross-coupling of DNA-conjugated aryl iodides with aliphatic amines. This protocol leverages a novel ligand, 2-((2,6-dimethoxyphenyl)amino)-2-oxoacetic acid, to effect the transformation in aqueous D
Selective Cross-Coupling of (Hetero)aryl Halides with Ammonia to Produce Primary Arylamines using Pd-NHC Complexes
Lombardi, Christopher,Day, Jonathan,Chandrasoma, Nalin,Mitchell, David,Rodriguez, Michael J.,Farmer, Jennifer L.,Organ, Michael G.
supporting information, p. 251 - 254 (2017/04/26)
Herein we report the first example of (hetero)arylation of ammonia using a monoligated palladium-NHC complex. The new, rationally designed, precatalyst (DiMeIHeptCl)Pd(allyl)Cl featuring highly branched alkyl chains has been shown to be effective in selective aminations across a range of challenging substrates, including nitrogen-containing heterocycles and those featuring base-sensitive functionality. The less bulky Pd-PEPPSI-IPentCl precatalyst performs well for ortho-substituted aryl halides, giving monoarylated products in high yield with good selectivity.

Synthesis of 1,2-diaryl- and 1-aryl-2-alkylimidazoles with sterically demanding substituents
Micksch, Maik,Tenne, Mario,Strassner, Thomas
, p. 6137 - 6145 (2013/09/24)
1,2-Diarylimidazoles are an important class of compounds. They are frequently used as ligands for photophysically active metal complexes and also display physiological activity. We developed a new, high-yielding procedure for the synthesis of 1,2-diaryl-s
Iron-catalyzed formation of 2-aminopyridines from diynes and cyanamides
Lane, Timothy K.,D'Souza, Brendan R.,Louie, Janis
, p. 7555 - 7563 (2012/11/07)
Diynes and cyanamides undergo an iron-catalyzed [2 + 2 + 2] cycloaddition to form highly substituted 2-aminopyridines in an atom-efficient manner that is both high yielding and regioselective. This system was also used to cyclize two terminal alkynes and
Substituent effects on aromatic stacking interactions
Cockroft, Scott L.,Perkins, Julie,Zonta, Cristiano,Adams, Harry,Spey, Sharon E.,Low, Caroline M. R.,Vinter, Jeremy G.,Lawson, Kevin R.,Urch, Christopher J.,Hunter, Christopher A.

Synthetic supramolecular zipper complexes have been used to quantify substituent effects on the free energies of aromatic stacking interactions. The conformational properties of the complexes have been characterised using NMR spectroscopy in CDCl3, and by comparison with the solid state structures of model compounds. The structural similarity of the complexes makes it possible to apply the double mutant cycle method to evaluate the magnitudes of 24 different aromatic stacking interactions. The major trends in the interaction energy can be rationalised using a simple model based on electrostatic interactions between the π-faces of the two aromatic rings. However, electrostatic interactions between the substituents of one ring and the π-face of the other make an additional contribution, due to the slight offset in the stacking geometry. This property makes aromatic stacking interactions particularly sensitive to changes in orientation as well as the nature and location of substituents.
