Mitsunobu








Common Conditions:


Aromatic Alcohols

Aromatic (phenolic) alcohols are the most common nucleophiles for Mitsunobu reactions. Reactions are typically done in THF with PPh3 and DEAD (or DIAD) at RT. Polymer supported PPh3 can be used to ease purification.[1]





Amides & Amide-like NH's

Amide NH's (or Amide-like NH's) that are sufficiently acidic can serve as nucleophiles in Mitsunobu reactions. Reactions are typically done in THF with PPh3 and DEAD (or DIAD) at RT. A common side reaction is the O-alkylation of the neighboring carbonyl(s). Polymer supported PPh3 can be used to ease purification.[1]





N-Heteroaryls

N-Heteroaryl NH's with sufficient acidity can undergo Mitsunobu reactions. Reactions are typically done in THF with PPh3 and DEAD (or DIAD) at RT. Polymer supported PPh3 can be used to ease purification.[1]





Azide

Diphenylphosphoryl azide (DPPA) is typically the source of azide for Mitsunobu reactions. Reactions are typically done in THF with PPh3 and DEAD (or DIAD) at RT. Polymer supported PPh3 can be used to ease purification.[1]
