In this study, the synthesis and characterization of new half-sandwich ruthenium complexes containing oxygen functionalised N-aryl and N-alkyl benzimidazol-2-ylidene ligands have been reported. All ruthenium complexes were tested as catalysts for a wide range of substrates in the N-alkylation of secondary cyclic amines such as pyrrolidine and piperidine, and 4-methylaniline which was a primary aromatic amine with alcohols by hydrogen-borrowing process. The catalytic reactions were performed with 1 mol% catalyst loading at 120 °C, 16 h under solvent-free conditions. All ruthenium complexes showed excellent catalytic activity, and N-alkylated products were obtained selectively.

A Mannich-like zinc-mediated three-component reaction of aromatic halides, amines, and paraformaldehyde is described. This procedure, which involves the in situ formation of arylzinc reagents, allows the straightforward synthesis of a range of functionalized tertiary benzylamines. Georg Thieme Verlag Stuttgart.

(Chemical Equation Presented) An array of α-branched amines has been prepared by using an expedient three-component Mannich-type reaction among organic halides, aldehyde derivatives, and amines. The experimental procedure, which is characterized by its simplicity, employs zinc dust for the in situ generation of organozinc reagents. We show that this Barbier-like protocol constitutes a useful entry to diarylmethylamines, 1,2-diarylethylamines, α- or β-amino esters, benzylamines, and β-arylethylamines.
