Silver thiolate nanoclusters as support for chiral ligands: application in heterogeneous phase asymmetric catalysis

Abstract

Silver thiolate nanoclusters have been functionalized with a chiral amino alcohol ligand that has previously shown high catalytic efficiency in different asymmetric reactions. The as-developed nanostructured catalyst, which can be easily recovered by simple centrifugation, has been tested in the addition of nitromethane to aromatic aldehydes, showing the same catalytic activity as the homogeneous ligand. Moreover, it was reused for two further recycling cycles without loss of efficiency. To the best of our knowledge, this is the first example of silver nanoclusters employed as a support for chiral ligands for heterogeneous phase asymmetric catalysis.
