The mitsunobu reaction
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). Although DEAD and DIAD are most commonly used, there are a variety of other azodicarboxylates available which facilitate an easi… WebJul 21, 2024 · The Mitsunobu reaction is a typical example of an \(S_N2\) reaction that takes advantage of phosphorus chemistry. The alcohol forms an excellent leaving group when it combines with the phosphine, and as the nucleophile displaces it in a typical \(S_N2\) reaction, which then undergoes an inversion of stereochemistry.
