Abstract

A series of novel 1-[(2,6-dichloro-4-trifluoromethyl)phenyl]-3-aryl-¹H-pyrazole-4-carbaldehydes were synthesized using the Vilsmeier-Haack reagent. The structures of all the title compounds have been confirmed by elemental analysis, ¹H-NMR and ¹³C-NMR and in addition, the structure of intermediate 5b was investigated by X-ray crystallography.
