2-Methoxy-3,4-diphenylphenol

Abstract

The title compound, C19H16O2, was isolated as the major product after the solid-state photochemical reaction of 2-methoxy-4,4-diphenylcyclohexa-2,5-dienone. The dihedral angles between the central ring and pendant benzene rings are 60.76 (6) and 51.64 (6)°. The O—C vector of the methoxy group is almost perpendicular to the plane of the central ring as indicated by the C—C—O—C torsion angle of 94.89 (18)°. Hydrogen-bonded dimers are formed in the crystal structure via O—H...O interactions. The data were collected at room temperature on a Bruker SMART X2S diffractometer in the automated mode and processed manually thereafter.
