1-Chloro-1-fluoroaryl-2-arylethylenes(Ⅲ) prepared from acetyl chloride with arones catalyzed by ZnCl2/SiO2, was dehydrochlorinated to afford diarylacetylenes containing fluorine with an overall yield of 24%~35%. The structures of the compounds were confirmed by IR spectroscopy and MS spectrometry. The influences of different fluorosubstituents on the melting point were investigated.
