  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.

  本发明提供了一种制备酰胺的方法，通过在Ruthenium催化剂的存在下反应一种一级胺和一种一级醇，生成酰胺和分子氢。根据本发明的方法，一级胺通过等摩尔量的醇直接酰化产生酰胺和分子氢（唯一的副产物），产率高，周转数高。这种反应由Ruthenium配合物催化，最好是基于公式A1的去芳香PNN型配体或其前体公式A2或A3。在反应中使用二胺会导致双酰胺，而使用混合的一级/二级胺底物，会发生一级胺基的化学选择性酰化。

  A process for preparing amides by reacting a primary amine and a primary alcohol in the presence of a Ruthenium complex to generate the amide and molecular hydrogen. 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. Also disclosed are processes for hydrogenation of amides to alcohols and amines; hydrogenation of organic carbonates to alcohols; hydrogenation of carbamates or urea derivatives to alcohols and amines; amidation of esters; acylation of alcohols using esters; coupling of alcohols with water and a base to form carboxylic acids; dehydrogenation of beta-amino alcohols to form pyrazines and cyclic dipeptides; and dehydrogenation of secondary alcohols to ketones. These reactions are catalyzed by a Ruthenium complex which is based on a dearomatized PNN-type ligand of formula A1 or precursors thereof of formulae A2 or A3.
