Allylic nitro compounds undergo relatively clean [2,3] sigmatropic rearrangement upon heating in refluxing 1,2-dichlorobenzene in the presence of DABCO to give the corresponding allylic alcohols via the intermediate allylic nitrite. [reaction: see text]

Solutions of α-mercapto-ketone anions, generated from O-ethyl S-2-oxoethyl dithiocarbonates and piperidine, react with cyanamides to give 2-aminothiazoles with substituents on the heterocycle or the exo-nitrogen atom.

The radical reaction between an N-ethylsulfonylenamide and an α-xanthyl ketone gives an intermediate γ-keto imine which spontaneously ring-closes to the pyrrole.

Xanthates have been readily converted into o-chlorophenyl thioethers using a one-step procedure conducted under radical conditions. In some selected cases, these aryl thioethers were successfully oxidized to the corresponding sulfoxides and sulfenic acid elimination afforded the corresponding vinylsilanes.
