Awarded the Nobel Prize in Chemistry in 1979, the Wittig reaction discovered by Dr. Georg Wittig in 1954, is one of the most widely used methods for the formation of carbon-carbon double bonds. Synthesized from aldehydes (or ketones) and the Wittig reagent (a triphenyl phosphonium ylide), numerous alkenes can be readily obtained.

For your convenience, J&K Scientific provides a wide range of reagents related to the Wittig reaction.
