Abstract

Au (III)-Schiff base complexes are active hydrogenation catalysts, giving turnover frequencies similar to those of the corresponding complexes of Pd(II), which has the same [d.sup.8] electronic structure as Au(III). Taking this into account, and by properly selecting the nature of solid supports (polarity and proton-donating ability), it is possible to strongly increase the activity of the homogeneous Au (III) and Pd (II) catalysts by grafting them onto the surface.
