A new and efficient protocol for the preparation of N-substituted anilines via an aromatization reaction was developed. 3,5-Dihydroxylcyclohexanone derivatives were used as the sources of the phenyl group and reacted smoothly with primary or secondary amines under mild conditions in the absence of metal catalyst and strong base. A variety of N-substituted anilines were prepared by this method with excellent yields up to 99%. The results indicate that this reaction begins with a nucleophilic addition.
A new class of easily activated palladium precatalysts for facile C-N cross-coupling reactions and the low temperature oxidative addition of aryl chlorides

A new class of one-component Pd precatalysts bearing biarylphosphine ligands is described. These precatalysts are air- and thermally stable, are easily activated under normal reaction conditions at or below room temperature, and ensure the formation of the highly active monoligated Pd(0) complex necessary for oxidative addition. The use of these precatalysts as a convenient source of LPd(0) in C-N cross-coupling reactions is explored. The reactivity that is demonstrated in this study is unprecedented in palladium chemistry.
