Abstract
The invention concerns a process transforming an aldehyde into a corresponding alkene, of the type wherein the aldehyde is placed in the presence of a phosphoric reagent and a base in an organic solvent. The process consists in using an alcohol as the solvent and as a base a mineral base which in an aqueous medium evinces a basic strength equal to or less than that of the hydroxide ion, or a strongly basic organic base of the amine family, and in limiting the hydration rate of the reaction medium to a value at most of 10 moles of water per mole of aldehyde.
