Abstract
Disubstituted bridged thiabicyclic ketosulfide was synthesized by propanone thiomethylation with a mixture of formaldehyde, sodium methylmercaptide, a nd sodium sulfide. An X-ray diffraction study showed the six-membered heter ocycle of 4-methyl-1-(methylthiomethyl)-7-thiabicyclo[3.3.1]non-3-en-2-one to be in the chair configuration and the substituted cyclohexene ring to ha ve the sofa configuration. The dihedral angle between two plane fragments o f the molecule is equal to 68.9 degrees.
