Under gas-liquid phase-transfer catalysis conditions, an aldehyde passed in the gaseous state through a solid bed of potassium carbonate and a phosphonium salt, results in the formation of an alkene which is obtained in good yield by condensation and is free from triphenylphosphine oxide, which remains adsorbed on the bed.

Abstract
Under gas-liquid phase-transfer catalysis conditions, an aldehyde passed in the gaseous state through a solid bed of potassium carbonate and a phosphonium salt, results in the formation of an alkene which is obtained in good yield by condensation and is free from triphenylphosphine oxide, which remains adsorbed on the bed.
