Abstract

Dendrimers are hyperbranched and well-defined macromolecules and have been attracting increasing attention over the past decade. A promising application of dendrimers is their use as soluble supports for the immobilization of homogeneous catalysts, particularly the often expensive chiral catalysts. In this review, chiral dendrimers bearing phosphorous units located at the core or on the periphery of the dendrimer will be described, focusing on their applications in the asymmetric catalytic hydrogenations. The catalyst recycling and the effects of the dendritic structure and size (generation) on the catalytic performance are discussed.
