Abstract: The title compound, C14H18BrFO, is a hexasubstituted tetrahydropyran with two halogen atoms attached in and four C substituents in positions with respect to the ether O atom. The CC distance [3.183 (7) Å] between the two 1,3-diaxially oriented -methyl groups falls below the sum of the van der Waals radii. The magnitude of the bond angle at oxygen [122.6 (3)°] and a comparatively small displacement of this atom [0.490 (5) Å] from the mean plane of four C atoms of the tetrahydropyran ring indicate a marked flattening of the heterocyclic ring in its 1C4 conformation.
