3-(5,6,7,8-Tetra-hydro-2-naphth-yl)iso-benzofuran-1(3H)-one.

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.

Project description:In the title compound, C16H15BrN2O4, the six-membered carbocyclic ring of the chromene moiety adopts an envelope conformation with the disordered methyl-ene C atom as the flap.
