Abstract: This paper describes a simple method for synthesizing pyrazoles from β-chlorovinyl ketones.Aseries of pyrazoles (3-halomethyl pyrazoles, 3-unsaturated alkyl pyrazoles, 3-(2-furyl) pyrazoles and 1-hydroxyethyl 3-alkylpyrazoles), have been synthesized by treating various β-chlorovinyl ketones with appropriate hydrazines. Yields are good in most cases.
