The Wittig Reaction or Wittig olefination is a chemical reaction of an aldehyde or ketone with a triphenyl phosphonium ylide to give an alkene and triphenylphosphine oxide. The reaction was given by George Wittig in 1950. He was awarded with Nobel Prize in 1979. The importance of Wittig reaction is that it provides a method for making carbon -carbon double bond formation in which the position of double bond formation is unambiguous. Otherwise, if we are using Grignard reagent positional isomers
