摘要
An easy, safe, solvent free and effective method for the synthesis of pyrazole-substituted chalcones has been achieved by grinding pyrazole aldehydes and acetophenones in the presence of activated barium hydroxide （C-200） in high yield within short span of time. All reactions were carried out just by grinding the two reactants in the presence of activated barium hydroxide （C-200）. Results are also compared with sodium hydroxide and potassium hydroxide.
