α-Haloesters containing the chalcone structure and α-haloamides containing the pyrazoline ring have been synthesized by reaction of substituted hydroxy chalcones and pyrazoline derivatives (prepared as reported elsewhere; J Chem 8(4):1574–1581, 2011) with chloroacetyl chloride in dry THF in the presence of Et3N. The structures of the synthesized compounds were confirmed by IR, 1H NMR, and (for some compounds) 13C NMR spectroscopy.
