Abstract
The synthesis and characterization by X-ray crystallography of the 1-methyl-exo, exo-3,5-dichloro-8-thiatricyclo[2.2.1.1.2,6]octane cation (II) is described. Compound II is prepared from the reaction of exo, exo-3,5-dichloro-8-thiatricyclo[2.2.1.1.2,6]octane (I) with trimethyloxonium tetrafluoroborate in nitromethane. Crystals of (II) belong to the space group, Pbca, with cell dimensions (298°K) of a=9.269(2) Å, b=12.112(3) Å, c=2.418(4) Å, V=2404.7(8) Å3, (Z=8. Solution and refinement of the intensity data gave final residuals of RF =5.60% and Rw =6.26% using 1289 unique reflections with (F0) > 3[sgrave] (F0).
