Input (English): The Schlosser modification of this reaction uses excess lithium salts, which stabilize the intermediate betaine created in the first step. The betaine forms an oxygen-containing four-membered ring, which subsequently breaks up into the products. A similarly named modification of this reaction stabilizes one of the reactants, forming the E form of the desired product almost exclusively. Named after the winner of the 1979 Nobel Prize in Chemistry, FTP, name this reaction, which forms an alkene from the reaction of a carbonyl group with a compound known as phosphorane or an ylide.
Output (English): Science
