An efficient ruthenium-catalyzed N-alkylation of amines, amides and sulfonamides was developed employing novel pentamethylcyclopentadienylruthenium(II) complexes bearing the methylene linked bis(NHC) ligand bis(3-methylimidazol-2-ylidene)methane. The acetonitrile complex I was proved to be particularly effective with a broad range of substrates with low catalyst loading (0.1-2.5 mol%) and high functional group tolerance under mild conditions. A total of 52 N-alkylated organonitrogen compounds including biol. relevant scaffolds were synthesized from (hetero)aromatic and aliphatic amines, amides and sulfonamides using alcs. or diols as alkylating agents in up to 99% isolated yield, even on gram-scale reactions. In the case of sulfonamides, it was the first example of N-alkylation employing a transition-metal complex bearing NHC ligands. In the experiment, the researchers used many compounds, for example, 4-(Benzylamino)benzonitrile (cas: 10282-32-3Product Details of 10282-32-3).
4-(Benzylamino)benzonitrile (cas: 10282-32-3) belongs to nitriles. Nitrile compounds can be prepared by the incorporation of a cyanide source through C–C bond formation or by dehydration of primary carboxamides. Industrially, the main methods for producing nitriles are ammoxidation and hydrocyanation. Both routes are green in the sense that they do not generate stoichiometric amounts of salts.Product Details of 10282-32-3
