6-[4-(tert-Butyldimethylsilyloxy)phenyl]-1-oxaspiro[2.5]heptane

Abstract

The title compound, C19H30O2Si, has triclinic (P\overline{1}) symmetry at 100 K. The O atom of the epoxide group has a pseudoaxial orientation and the dihedral angle between the cyclohexyl and benzene rings is 85.80 (8)°. The C—O—Si—Ct (t = tert-butyl) torsion angle is −177.40 (14)°. In the crystal, pairwise C—H...O links connect the molecules into inversion dimers featuring R22(8) loops.
