چکیده

A simple, mild and efficient method for the regioselective nitration of various aromatic compounds using
poly(4-vinylpyridinium nitrate) (P4VPyN) in the presence of melamine trisulfonic acid (MTSA), is reported.
This method provides several advantages such as good selectiveity between ortho and para positions of
aromatic compounds, clean procedure, simple work-up, short reaction times, solvent-free conditions and
high yields of products. This methodology is useful for nitration of activated and deactivated aromatic rings.
