In the previous work, we reported the synthesis of ylids and phosphoranes obtained from an addition reaction between a phosphhite or an aminophosphine and dimethylacetylene dicarboxylate in presence of a protic trapping reagent. This present work is devoted to the elaboration of the various mechanistic schemes involved in these reactions in connection with their stereochemical aspect.
