3-trans-Bromo-5-cis-fluoro-2,6,6-trimethyl-2-phenyl­tetra­hydro­pyran

The title compound, C₁₄H₁₈BrFO, is a hexa­substituted tetra­hydro­pyran with two halogen atoms attached in β and four C substituents in α positions with respect to the ether O atom. The C...C distance [3.183 (7) Å] between the two 1,3-diaxially oriented α-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.
