The reaction of (pentamethylcyclopentadienyl)iridium dichloride dimer, [IrCp*Cl2]2, with bis(2,4,6-trimethylphenyl) formamidine allows the preparation of two new [IrCp*Cl 2(amidine)] and [IrCp*Cl(amidinate)] complexes, which have been fully characterized. Both complexes have been tested in the β-alkylation of 1-phenylethanol with primary alcohols, and in the formation of tertiary amines from the reaction of ammonium salts with primary alcohols, and the results have been compared with those shown by Shvo's catalyst. Our studies demonstrate that both [IrCp*Cl2(amidine)] and Shvo's catalyst are very efficient in both catalytic processes. The high activity of the Ir-amidine complex may be attributed to the presence of the NH group in the amidine ligand. Copyright

Rh-catalyzed one-step synthesis of tertiary and secondary amines from aldehydes and ketones, ammonium carbonate serving as nitrogen source, and carbon monoxide as a reducing agent has been developed. Aliphatic and aromatic aldehydes lead to the corresponding tertiary symmetrical amines in 69–83 % yields. Aromatic and aliphatic ketones lead to the corresponding secondary symmetrical amines which were obtained in 62–79 % yields.

Urea, the white gold: The efficient synthesis of tertiary and secondary amines is achieved by heterogeneous gold-catalyzed direct amination of stoichiometric alcohols with urea in good to excellent yields. Via a hydrogen autotransfer pathway, the reactions of primary alcohols with urea give tertiary amines exclusively, while secondary alcohols selectively afford secondary amines.
