Concept introduction:
A molecule that is phosphorus-stabilized carbanion is an ylide. This molecule does not have overall charge, but is consist of negatively charged carbon atom bonded to a positively charged heteroatom. Phosphorus ylides are produced from alkyl halides and tri-phenylphosphine. The product that is prepared is an alkyltriphenylphosphonium salt.

Phosphorus ylides are produced from alkyl halides and tri-phenylphosphine. The product that is prepared is an alkyltriphenylphosphonium salt.
In the Witting reaction, the carbonyl group of a ketone or aldehyde get converted in to new carbon-carbon double bond by the reaction with phosphorus ylide.
