MAGNETIC NANOPARTICLES FOR ORGANIC SYNTHESIS AND METHOD THEREOF

摘要

A surface-modified, magnetic nanoparticle has one or more multi-dentate ligands bound to a surface of a magnetic nanoparticle. The one or more multi-dentate ligands are bound to the surface of the magnetic nanoparticle through one or more dithiocarbamate groups. The one or more multi-dentate ligands may be a compound of Formula II: R2NCH2[CH2NR′CH2]m[CH2N(CS2−)CH2]q[CH2NHCH2]rCH2NR″2   (II) where each R, R′, and R″ are independently H, a branched ethyleneimine unit, an unsubstituted or substituted alkyl, an unsubstituted or substituted alkenyl, or an unsubstituted or substituted aryl; and n is an integer from 1 to about 50.
