Full-matrix least-squares refinement (non- hydrogen atoms anisotropic, H atoms isotropic) based on 2535 reflexions led to a final R of 0.078. The geometries around the two S atoms are pyramidal (tetrahedral when the lone pair is considered) and the molecules exhibit R,R and S,S stereochemistries which © 1979 International Union of Crystallography 3120 (+)-3-BIS(PHENYLSULFINYL)METHYL- 1,2-DIMETHYLCYCLOPROPENE is consistent with the diastereoisomeric (+) for- mulation. Introduction. Sulfinyl carbenes are a new and largely unstudied class of organic reactive intermediates (Venier, Barager & Ward, 1975). In a study of their reactions with
