The use of alkaline carbonates in a slighty hydrated solid-liquid protic organic media allowed the synthesis of alkenes from polyfunctional aldehydes with high yield in a E preferential stereochemistry specially with non-stabilized ylides.It has been shown that the decomposition of the threo betain acts as the determining step of the reaction.

The use of alkaline carbonates in a slighty hydrated solid-liquid aprotic organic media allowed the synthesis of alkenes from polyfunctionnal aldehydes or activated ketones with high yield in a Z preferential stereochemistry.The reaction mechanism proposed takes in account the specific use of water on the solvation of cationic species at the solid-liquid interface to explain the Z.E alkene ratio.
