| 549493000 | The nitrogen is bonded directly to a -C(=X)- group, wherein X is chalcogen | 1 |
| 20090112005 | PROCESS FOR PREPARING AMIDES FROM ALCOHOLS AND AMINES - The present invention provides a process for preparing amides, by reacting a primary amine and a primary alcohol in the presence of a Ruthenium catalyst, to generate the amide and molecular hydrogen. According to the process of the invention, primary amines are directly acylated by equimolar amounts of alcohols to produce amides and molecular hydrogen (the only byproduct) in high yields and high turnover numbers. This reaction is catalyzed by a Ruthenium complex, which is preferably based on a dearomatized PNN-type ligand of formula A1 or precursors thereof of formulae A2 or A3. Use of diamines in the reaction leads to bis-amides, whereas with a mixed primary/secondary amine substrate, chemoselective acylation of the primary amine group occurs. | 04-30-2009 |
