The Mitsunobu reaction is an organic reaction that converts an alcohol into a variety of functional groups, such as an ester, using triphenylphosphine and an azodicarboxylate such as diethyl azodicarboxylate (DEAD) or diisopropyl azodicarboxylate (DIAD) The alcohol undergoes an inversion of stereochemistry. It was discovered by Oyo Mitsunobu (1934–2003).
