Regioselective brominations of aromatic compounds using Propylsulfamic acid supported onto magnetic Fe۳O۴ nanoparticles (MNPs-PSA) as a green and reusable heterogeneous nanocatalyst

A Regioselective brominations of aromatic compounds by a simple method reaction in the presence of a catalytic amount of N-Propylsulfamic acid supported onto magnetic Fe۳O۴ nanoparticles (MNPs-PSA) under solvent free is reported. The magnetic nanocatalyst can be readily recovered easily by applying an external magnet device and reused for at least ۱۰ reaction runs without considerable loss of reactivity. The structures of the compounds were confirmed by IR, ۱H NMR, ۱۳C NMR, and elemental analysis.
