Abstract: The reaction of 1-phenyl-3-trifluoromethyl-2-pyrazolin-5-one and 2-chlorobenzaldehyde leads to the title compound, which results from addition of a second pyrazolone unit to the primarily formed 1:1 condensation product. Detailed spectroscopic data (¹H NMR, ¹³C NMR, ¹⁹F NMR, IR, MS) are presented.

Keywords: 3-trifluoromethyl-2-pyrazolin-5-one; condensation; NMR spectroscopy
