Abstract:
The title compound, C(18)H(16)O(2), was prepared by reduction of 2-(5,6,7,8-tetra-hydro-2-naphtho-yl)benzoic acid with zinc dust. The benzene ring in the tetra-hydro-naphthyl substituent is nearly perpendicular to the plane of the isobenzofuran-1(3H)-one ring [87.15 (4)°]. The cyclo-hexane unit has a half-chair conformation in which two methylene groups in the tetra-methyl-ene bridge are disordered over two positions; the site-occupancy factors are 0.838 (4) and 0.162 (4). The crystal structure exhibits alternating isobenzofuran-1(3H)-one and tetra-hydro-naphthalene layers.

Nomenclature of Aromatic Compounds with Multiple Substituents
For disubstituted benzene derivatives, with two groups attached to the benzene ring, three constitutional isomers are possible. For example, consider dimethyl benzene, often called xylene, where the second methyl group can be substituted at the second, third, or fourth carbon. The relative position of the substituents is represented by prefixes ortho, meta, or...
