The facile synthesis of valuable primary and secondary amines is reported using a sequential procedure of hydroaminomethylation and Pd-catalyzed hydrogenolysis. The hydroaminomethylation reaction was catalyzed by a cationic Rh(I) iminopyridyl complex and the N-alkylated benzylamines were produced with high chemoselectivity, albeit as mixtures of linear and branched products. Performing the hydrogenolysis reaction using 10% Pd/C, provided access to valuable primary and secondary amines which have applications in the surfactant, pharmaceutical and polymer industries.

Symmetric secondary amines were synthesized by the self-condensation of primary amines over a palladium-loaded titanium dioxide (Pd/TiO2) photocatalyst. The reactions afforded a series of secondary amines in moderate to excellent isolated yields at ambient temperature (30 °C, in cyclopentyl methyl ether). Applicability for one-pot pharmaceutical synthesis was demonstrated by a photocatalytic reaction sequence of self-condensation of an amine followed by N-alkylation of the resulting secondary amine with an alcohol.

Symmetrical tertiary amines have been efficiently realized from amine and secondary amines via deaminated homocoupling with heterogeneous bimetallic Co2Rh2/C as catalyst (molar ratio Co:Rh=2:2). Unsymmetric secondary anilines were produced from the reaction of anilines with symmetric tertiary amines. The Co2Rh2/C catalyst exhibited very high catalytic activity towards a wide range of amines and could be conveniently recycled ten times without considerable leaching. (Figure presented.).
