A cascade process for the straightforward one-pot conversion of β-ketonitriles into β-hydroxyamides is presented. The process, that proceeds in water employing the arene-ruthenium(II) complex [RuCl2(η6-p-cymene){P(4-C6H4F)2Cl}] as catalyst in combination with sodium formate, involves the initial hydration of the β-ketonitrile substrates to generate the corresponding β-ketoamide intermediates, which subsequently undergo the transfer hydrogenation (TH) of the carbonyl group. Employing a family of forty different β-ketonitriles, featuring diverse substitution patterns, the scope and limitations of the process have been established.

An unprecedented hydration/transfer hydrogenation tandem process for the catalytic conversion of β-ketonitriles into synthetically useful β-hydroxyamides in water has been developed, making use of the ruthenium(II) complex [RuCl2(η6-

Chitin-supported ruthenium (Ru/chitin) promotes the hydration of nitriles to carboxamides under aqueous conditions. The nitrile hydration can be performed on a gram-scale and is compatible with the presence of various functional groups including olefins, aldehydes, carboxylic esters and nitro and benzyloxycarbonyl groups. The Ru/chitin catalyst is easily prepared from commercially available chitin, ruthenium(III) chloride and sodium borohydride. Analysis of Ru/chitin by high-resolution transmission electron microscopy indicates the presence of ruthenium nanoparticles on the chitin support.
