Abstract
In the title compound, C19H19BrO2, the cyclohexenone ring adopts an envelope conformation with the C atom bearing the methyl substituents as the flap. In the crystal, weak π–π stacking is observed between parallel aromatic rings of adjacent molecules, the centroid–centroid distance being 3.694 (6) Å. The entire bromonaphthylmethyl unit is disordered over two orientations, with a site-occupancy ratio of 0.5214 (19):0.4786 (19).
