This reaction features a short-lived four-membered ring intermediate, which forms during the spontaneous decomposition of the initial intermediate, a neutral, dipolar compound known as a betaine [BAY-ta-een].  The essential reagent for this reaction, a neutral compound with adjacent positive and negative charges, possesses a strongly nucleophilic carbon that attacks the carbon of a carbonyl to form the desired product plus a triphenylphosphine oxide.  Used to create an alkene from a ketone or aldehyde, FTP name this reaction that requires the use of a phosphorus-stabilized carbanion known as an ylide [ILL-id], named for the winner of the 1979 Nobel Prize in Chemistry.
