The reaction of [RuCl2(p-cymene)]2 with in situ prepared Ag-N-heterocyclic carbene (NHC) complexes yields a series of [RuCl2(p-cymene)(NHC)] complexes (2). All of the complexes have been characterised by elemental analysis, and 1H NMR and 13C NMR spectroscopies. These complexes have been tested for the N-alkylation of aromatic amines with arylmethyl alcohols under neat conditions in the presence of KOtBu at 120 °C. Compounds (2) are stable and have high catalytic/selective activity for the N-alkylation reactions of primary amines to afford secondary amines.

This invention is a novel bismuth organic complex and its preparation method and catalytic applications. Characterized in that in order to commonly used organic solvent as a reaction solvent, in order to organic bismuth ion nitrogen atom ligand diphenyl [...] and cheap and easy to obtain aryl boric acid as the raw material, the nickel acetate catalytic reaction, high yield, high selectivity to obtain a novel bismuth organic (III) complex catalyst (I). The good stability of the catalyst, can be recovered, and in the catalytic aryl alkynes and aniline derivatives hydroamination reaction demonstrate excellent catalytic activity. This method has the advantages of low cost, high yield, simple and convenient operation, no pollution and the like, for the realization of its industrial production has certain feasibility.
