What is Ylides. Ylides in organic synthesis. Stability of Ylides. Wittig reaction mechanism. Applications. Problem with solution. A ylide is a neutraldipolar molecule containing a formally negatively charged atom, usually a carbanion directly attached to a heteroatom with a formal positive charge, usually nitrogen, phosphorus or sulfur, and in which both atoms have full octets of electrons. Ylides are thus 1,2-dipolar compounds, and a subclass of zwitterions. They appear in organic chemistry as reagents or reactive intermediates. Wittig reaction The Wittig reaction is a chemical reaction of an aldehyde or ketone with a triphenyl phosphonium ylide (often called a Wittig reagent) to give an alkene and triphenylphosphine oxide. The Wittig reaction was discovered in 1954 by Georg Wittig, for which he was awarded the Nobel Prize in Chemistry in 1979.
