The Wittig reaction carried out in a slighty hydrated solid-liquid media constituted by a solid alkaline hydroxyde and an organic phase which includes the phosphonium salt and the aldehyde leads easily to the corresponding alkene with very good yields specially with furanic aldehydes. The ylide formation at the interface appears as the most important step of this condensation.
