  Catalyst systems consisting of supported or unsupported transition metal catalysts which have modifiers on the surface. The modifiers have sulphur-containing functionalities (G 0 ). In addition, the modifiers may have a spacer (Sp) and a Bronsted-basic, Bronsted-acidic or Lewis-basic functionality (G 1 ). The catalyst systems may be used for hydrogenation, reductive alkylation and reductive amination.
