recommendations! Published in 2018 at "Applied Organometallic Chemistry"

DOI: 10.1002/aoc.3925

Abstract: Magnetically recoverable and environmentally friendly Cu-based heterogeneous catalyst has been synthesized for the one-pot conversion of aldehydes to their corresponding primary amides. The Fe3O4@SiO2 nanocomposites were prepared by synthesis of Fe3O4 magnetic nanoparticles (MNPs) which… read more here.
