Article abstract of DOI:10.1016/S0040-4020(01)96527-5

Wittig, Wittig-Horner and Knoevenagel reactions are achieved in the presence of alumina or potassium fluoride supported on alumina, without organic solvent.The presence of a small amount of water increases the rate of the Wittig and Wittig-Horner reactions.The reaction of the diethyl cyanomethylphosphonate with an aldehyde in the presence of dry alumina is oriented towards the Knoevenagel reaction.
