Ethyl 2-(4-methylbenzoyl)-2,3-dihydro-1H-indene-2-carboxylate

J. Xiang, T. Hu and J. Wang

Abstract: The title compound, C20H20O3, contains two fused rings with a quaternary carbon centre connecting p-toluoyl and ethoxycarbonyl groups. The dihedral angle between the fused benzene ring and the three-C-atom plane (derived from O=C-C-C=O) is 82.5 (4)°, whereas the dihedral angle between the planes of the benzene rings is 53.4 (2)°. In the crystal, molecules are linked via C-H...Oester hydrogen bonds, forming chains propagating along [010].
