Amination of Aryl Boronic Acids with Alkylnitrites: A Convenient Complement to Cu-Promoted Reductive Amination

Copper-catalyzed amination of aryl boronic acids with alkylnitrites leading to symmetrical diarylamines with a practical 50-80% yield was elaborated. Two C(sp2)-N bonds are formed in the one-pot process under mild conditions. This new approach to diarylamines is a complement to the Cu-assisted reductive amination of aryl boronic acids avoiding preliminary synthesis of nitrosoarenes. The possible reaction scheme based on quantum chemical calculations was suggested, clarifying key intermediates.

Formal arylation of NH3 to produce diphenylamines over supported Pd catalysts

In the presence of supported Pd nanoparticle catalysts, e.g., Pd/Al2O3, various diphenylamines could be synthesized through acceptorless formal arylation using NH3 or its surrogates, e.g., urea, as nitrogen sources and cyclohexanones as arylation sources. The observed catalysis was truly heterogeneous, and the catalyst was reusable with retention of its high catalytic performance.
