Diphenylphosphine Chemical Properties,Uses,Production

Organophosphorus compound

Diphenylphosphine is commonly used in laboratory as organic phosphorus compound, it is unpleasant odor colorless liquid, and it is pungent, it is easily oxidized in air and can cause spontaneous combustion, it is sensitive to air and light, it need the protection of nitrogen. It can be used as precursor to synthesize some organic phosphine ligand. By deprotonation, it can be converted to diphenylphosphine compound: Ph2PH + nBuLi → Ph2PLi + nBuH, such as 1,2-bis (diphenylphosphino) ethane and 1,3-bis (diphenylphosphino) propane phosphine ligands etc, Wittig-Horner reagents and the synthesis of quaternary phosphonium salt is usually by means of diphenylphosphino alkylation to achieve.
Diphenylphosphine such as sodium and lithium diphenylphosphine and diphenylphosphine compound can add to carbon heteroatom double bond as nucleophile. For example, in the condition of concentrated hydrochloric acid at 100℃, diphenylphosphine can add to aldehyde carbon atoms of benzaldehyde: Ph2PH + PhCHO → Ph2P (O) CH2Ph, when compares with tertiary phosphine, alkalinity of diphenylphosphine is weaker. The pKa of conjugate acid diphenylphosphine is 0.03: Ph2PH2 + → Ph2PH + H +
Preparation: Lithium diphenylphosphine can generated by inexpensive triphenylphosphine and the with the cancellation of water can obtain diphenylphosphine: (1) PPh3 + 2 Li → LiPPh2 + LiPh (2) LiPPh2 + H2O → Ph2PH + LiOH.
