Trialkylamines are made by the action of hydrogen on a dialkylamine and a ketone in the presence of a metal sulfide catalyst. E.g., hydrogenation of a mixture of dibutylamine and cyclohexanone, using platinum sulfide catalyst, produces N,N-dibutylcyclohexylamine.

The selective cleavage of thermodynamically stable C(sp3)−C(sp3) single bonds is rare compared to their ubiquitous formation. Herein, we describe a general methodology for such transformations using homogeneous copper‐based catalysts in the presence of air. The utility of this novel methodology is demonstrated for Cα−Cβ bond scission in >70 amines with excellent functional group tolerance. This transformation
