Abstract: 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.

Abstract: The present invention provides a system and method of storing hydrogen (H2) and releasing it on demand, comprising and making use of diaminoalkanes and alcohols, or aminoalcohols as liquid-organic hydrogen carrier systems (LOHC). 2-amino-ethanol (AE) or its N-methyl derivative 2-(methylamino)ethanol undergo catalytic dehydrogenation to form a cyclic dipeptide (glycine anhydride—GA) or its N,N-dimethyl derivative (N,N-dimethyl GA) with release of hydrogen. Similarly, ethylenediamine (ED) and ethanol undergo catalytic dehydrogenation to form N,N′-diacetylethylenediamine (DAE) with release of hydrogen. Glycine anhydride (GA) or N,N-dimethyl-GA may be hydrogenated back to 2-aminoethanol (AE) or 2-(methylamino)ethanol, respectively, each of which functions as a hydrogen storage system. N,N′-diacetylethylenediamine (DAE) may be hydrogenated back to ED and ethanol, which functions as a hydrogen storage system. These reactions may be catalyzed by a variety of compounds or complexes, including Ruthenium complexes as described herein.
