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 degrees C, 16 h under solvent-free conditions. All ruthenium complexes showed excellent catalytic activity, and N-alkylated products were obtained selectively.eninfo:eu-repo/semantics/closedAccessN-Heterocyclic carbeneRutheniumN-Alkylation of aminesHydrogen-borrowing processArticle49810.1016/j.ica.2019.1191632-s2.0-85072639878Q2WOS:000501778900019Q2
