Reaction of 3-dimethylaminoprop-2-enal with a reagent, prepared from dimethyl sulfide and N-chlorosuccinimide, afforded (l-formyl-2-dimethylaminoethenyl) dimethylsulfoni urn chloride (V) which was hydrolysed to a highly stabilised sulfonium ylide- dimethylsulfoniodiformylmethylide. The properties of this yJide are compared with those of its nitrogen analogue-trimethyJammoniodiformylmethylide. Cyclisation reactions of the ...
