Abstract
The title compound, C19H12ClF3O3, obtained by the photochemical transformation of 2-[5-chloro-2-(prop-2-ynyloxy)benzoyl]-3-[4-(trifluoromethyl)phenyl]oxirane adopts a Z conformation with respect to the enolic C=C double bond. The dihedral angle between the benzene rings is 12.25 (16)° and an intramolecular O—H⋯O hydrogen bond closes an S(6) ring. An intramolecular C—H⋯O interaction also leads to an S(6) ring. In the crystal, very weak C—H⋯O interactions and short Cl⋯Cl contacts [3.3221 (16) Å] are seen, as well as weak aromatic π–π stacking interactions [centroid–centroid separation = 3.879 (2) Å].
