Synthesis of acetyl pyrazoline derivatives under solvent–freeconditions

A number of acetyl pyrazoline derivatives were synthesised by the condensation ofpyrazoline derivatives with acetyl chloride under solvent-free conditions at room temperature.The products were obtained after simple work-up in high yields and purity and characterized bytheir IR and NMR spectral data.
