| Abstract: | The stabilization of phosphorothiolate carbanions has been achieved. Condensation of these carbanions with carbonyl derivatives lead to the corresponding α,β-unsaturated esters; a mechanism, via a β-hydroxyphosphorothiolate-β-mercaptophosphate rearrangement, is described. These new synthons are compared with the phosphonate analogs (Wittig-Horner's reagent). |
