Asymmetric reactions of chiral organo-magnetic nanoparticles (original) (raw)

Applied Catalysis A: General, 2015

Abstract

Abstract Magnetic nanoparticles (MNPs) have been widely used as a catalytic supports. MNPs have high surface-area that allows the design and setup of many catalytic sites. Their surfaces can be modified with chiral organocatalyst (COC) to become a sustainable catalytic material. This functionalized magnetite can be easily separated using an external magnet after reaction. We summarize the use of COC-MNPs which are robust and readily available for chiral transformation. The catalytic activity, recyclability, and immobilization method of COC-MNPs are described. The catalytic load, size of the particles, solvent system, ee values and de ratios are also evaluated on each asymmetric reaction.
