A new method for the synthesis of thioaldehyde and thioketone S-oxides by an unusual base-induced β-elimination of chloroform from readily available allylic and benzylic trichloromethyl sulfoxides is described. The reaction proceeds smoothly under mild conditions. The facile preparation of α,β-unsaturated sulfines by the new method is of special interest. A possible mechanism for this remarkable sulfine

A new method for the synthesis of thioaldehyde S-oxides by base-induced elimination of chloroform from allylic and benzylic trichloromethyl sulfoxides is described. The reaction proceeds smoothly under mild conditions. A mechanism for this remarkable sulfine synthesis and apparently unprecedented β-elimination of chloroform is presented.
