Triphenylphosphine
Name Reactions
Recent Literature
A new, mild protocol for deoxygenation of various phosphine oxides with
retention of configuration is described. Mechanistic studies regarding the
oxygen transfer between the starting phosphine oxide and triphenylphosphine
are also presented.

A rhodium-catalyzed methylenation-hydrogenation cascade process allows the
homologation of carbonyl compounds to alkanes in high yields.

In the presence of Ph3P and a catalytic amount of Fe(TCP)Cl, ketenes
react with EDA to give allenes in high yields under neutral conditions. By
employing a chiral phosphine, allenes could be synthesized with high
enantioselectivity in good yields.

Alkyl nitrites were prepared in good to excellent yields by treatment of
alcohols and thiols with
triphenylphosphine/2,3-dichloro-5,6-dicyanobenzoquinone/Bu4NNO2 in acetonitrile.
This method allows a selective conversion of primary alcohols in the presence of secondary and tertiary alcohols and thiols.
