Abstract

Abstract : The catalytic activity of a linear β-amino alcohol ligand anchored on functionalized magnetite/silica core–shell nanoparticles has been evaluated in the addition of dialkylzinc to aldehydes leading to promising results. Abstract : A linear β-amino alcohol ligand, previously found to be a very efficient catalyst for enantioselective addition of dialkylzinc to aromatic aldehydes, has been anchored on differently functionalized superparamagnetic core–shell magnetite–silica nanoparticles (1a and 1b ). Its catalytic activity in the addition of dialkylzinc to aldehydes has been evaluated, leading to promising results, especially in the case of 1b for which the recovery by simple magnetic decantation and reuse was successfully verified.
