4) Production of Diphenylphosphine

Diphenylphosphine can be got from the reaction from the of diphenylphosphine chloride tetrahydro aluminum lithium. The intermediates and the organic phosphorus compound can be prepared Top phosphine ligand.

In addition, Diphenylphosphine can be prepared cheaply from triphenylphosphine. The reaction of it is as follows:

PPh₃ + 2 Li → LiPPh₂ + LiPh
LiPPh₂ + H₂O → Ph₂PH + LiOH

5) Applications of Diphenylphosphine

Diphenylphosphine is a precursor to organophosphorus ligands for use as catalysts. In the laboratory, diphenylphosphine is a common intermediate. It can be deprotonated to give diphenylphosphide derivatives: Ph₂PH + nBuLi → Ph₂PLi + nBuH. Diphenylphosphine and especially diphenylphosphide derivatives are nucleophiles, so they add to carbon – heteroatom double bonds. Diphenylphosphine can be used as organic intermediate or catalyst.
