This reaction is known as
Wittig Reaction. A powerful reaction for the synthesis of
Alkene. In question the starting materials are
aldehyde and a Phosphorous
Ylide. Ylide when reacted with aldehyde produces a four membered ring which on
rearrangement gives Alkene and triphenylphosphine oxide. Phosphorous having great
affinity toward the oxygen is the driving force of this rearrangement. The reaction along with product (highlighted
blue) is as follow,
