A solvent-free method for the synthesis of novel p-nitrophenyl hydrazones
was successfully developed. The condensation of the p-nitrophenyl hydrazine
with aromatic aldehydes through this mechanochemical technique furnished
three products 3a-c with moderate to high yield. The developed method is
eco-friendly, efficient, simple, and convenient, and indicated high
reproducibility, short reaction time, catalyst-free, simple workup, and
afforded pure and unsolvated products.
