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.
