In the title molecule, C16H10F3NO, the N-bound phenyl ring is oriented nearly orthogonal to the quinolinyl ring in order to avoid steric clashes with the trifluoromethyl substituent [dihedral angle 89.7 (1)°].

The synthesis of (I) has been described by Usachev & Sosnovskikh (2004); also see Sosnovskikh et al. (2005). In the present study, (I) was obtained as a side-product when the thione was recrystallized from THF in the presence of copper(II) chloride.
Carbon-bound H atoms were included in the
in the riding-model approximation with C—H = 0.93 Å, and with Uiso(H) 1.2Ueq(C).Compound (I) was isolated during an attempted reaction of the corresponding thione with CuCl2 in THF solution, see Experimental. The N-bound aromatic ring in (I) occupies a position orthogonal to the quinolinyl ring so as to avoid steric clashes with the adjacent CF3 group, Fig. 1.

Compound (I) was isolated during an attempted reaction of the corresponding thione with CuCl2 in THF solution, see Experimental. The N-bound aromatic ring in (I) occupies a position orthogonal to the quinolinyl ring so as to avoid steric clashes with the adjacent CF3 group, Fig. 1.
