A highly efficient and environmentally friendly method has been developed for facile synthesis of 3,5-diphenyl-1H-pyrazoles under mechanochemical ball-milling conditions. The advantages of short reaction time, high efficiency, no separation of in situ generated intermediate, using cheap sodium persulfate as the oxidant, together with very simple work-up procedure, make this one-pot and solvent-free protocol a green and powerful alternative to traditional methods for the synthesis of these kinds of compounds.

Chalcones were prepared from substituted acetophenones and substituted benzaldehydes and condensed with hydrazine hydrate in ethanol to get the corresponding pyrazolines (Pdc1 to Pdc 14). The compounds were synthesized and characterizes by TLC, melting po

Some new pyrazolines (III,IV) have been prepared by the reaction of chalkones with hydrazines.The new pyrazolines have been converted into different derivatives.The hitherto unknown reaction of pyrazolines with phthalic anhydride has also been described.
