2-Phosphoryl-(2-4), 2-sulfinyl-(5) and 2-sulfonyl-2,3-alkadienoates (6 and 7) were prepared in an one-pot reaction by a [2,3]-sigmatropic rearangement of the heteroatom-substituted 2-alkynoates obtained from ethyl propynoate and subsequent treatment with lithium diisopropylamide, ketone, trimethylchlorosilane and phosphorus- or sulfur-containing chloride.
