Only a few examples of thermal [2+2+2] cycloadditions are reported [2] where a C-C single bond participates as a two-electron component. To our knowledge no reaction is known in which an electron-rich C-C single bond is involved In
Previously we described the efficient oxidation of l-methoxycyclopropanol 1 with Cu\*+ Ions to methyl acrylate 2 and dimethyl adipate 3 via the methyl P-propionate radical 2. It was proved by labelling experiments 131 that the \*
## Abstract 1βHydroxyβ and 1βhalocyclopropyl sulfides can be conveniently prepared starting from cyclopropanone. Cyclopropyl sulfides with halogen or a dimethylsulfonium group in the Ξ±βposition can be transformed into 1βsubstituted cyclopropyl sulfides with a variety of nucleophiles. This means tha
