, p. 9415 - 9423 (2020/08/14)
An elemental sulfur-promoted aerobic dehydrogenation system for the access to N,N′-dialkyl-o-phenylenediamines and N-substituted 2-naphthylamines is reported herein. Readily available cyclohexanones and amines (especially alkylamines) are transformed smoo

The first heterogeneous catalyzed oxidative coupling of aryl amines is reported. Aryl amines were dimerized at room temperature under air using a heterogeneous Rh/C catalyst in the presence of acids. By choosing a suitable acidic solvent, biaryl compounds and carbazoles were selectively prepared in good yields. This reaction is operationally simple and provides an effi cient synthetic methodology for the preparation of biaryl diamines via oxidative C - H activation.

experimental part, p. 1097 - 1105 (2010/08/06)
A simple and efficient copper-catalyzed method has been developed for N-arylations of nitrogen-containing heterocycles and aliphatic amines in water. The protocol uses (1E,2E)-oxalaldehyde dioxime (OADO) as the ligand, and water as the solvent, and shows good tolerance towards various functional groups.
