In the title compound, C27H22O2, the acetyl group is nearly coplanar with the the ring to which it attacted [O-C-C-C torsion angle = -5.5 (3)°]. The three phenyl groups of the triphenylmethyl substituent are mutually nearly perpendicular, making dihedral angles of 89.87 (11) and 78.29 (11) and 60.34 (11)°. Two intramolecular C-H O hydrogen bonds occur. In the crystal, C-H O hydrogen bonds link the moleclues into chains along the b-axis direction.
