selective hydrogenation of aromatic and aliphatic nitriles into amines and imines is described. Using a ruthenium pincer complex, the selectivity towards amines or imines can be controlled by simple parameter changes. The reactions are conducted under very mildconditions between 50–100 °C at 0.4 MPa H2 pressure without any additives at low catalytic loadings of 0.5–1 mol %, which results in quantitative conversions

The present invention relates to a method for manufacturing an imine having no substituent group on the nitrogen by using, as a catalyst, a metal complex on an organic azide compound, and more specifically relates to a method in which a metal-complex catalyst is used to produce, from an organic azide having an alpha-hydrogen, an imine having no substituent group on the nitrogen via a continuous nitrogen removal and 1,2-hydrogen transfer reaction. The imine having no substituent group on the nitrogen manufactured by means of the method of the present invention can synthesise diverse coupling products comprising amine compounds by means of reactions with diverse nucleophiles.
