Diad pph3 mechanism
Triphenylphosphine (IUPAC name: triphenylphosphane) is a common organophosphorus compound with the formula P(C6H5)3 and often abbreviated to PPh3 or Ph3P. It is widely used in the synthesis of organic and organometallic compounds. PPh3 exists as relatively air stable, colorless crystals at room temperature. It dissolves in non-polar organic solvents such as benzene and diethyl ether. WebAmides & 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 …
