FACILE REDUCTION OF ORGANIC HALIDES AND PHOSPHINE OXIDES WITH LiAlH4-CeCl3
Imamoto, Tsuneo,Takeyama, Toshiaki,Kusumoto, Tetsuo
, p. 1491 - 1492 (1985)
A new reagent system, LiAlH4-CeCl3, exhibits powerful and characteristic reducing ability.Organic halides including fluorine compounds are smoothly dehalogenated with this reagent.Phosphine oxides are also reduced to phosphines in excellent yields.
P-stereogenic phosphorus compounds: Effect of aryl substituents on the oxidation of arylmethylphenylphosphanes under asymmetric appel conditions
Rajendran, Kamalraj V.,Kennedy, Lorna,Gilheany, Declan G.
experimental part, p. 5642 - 5649 (2010/12/25)
The effects of aryl ring substitution on the dynamic resolution of aryl(methyl)phenylphosphanes under asymmetric Appel reaction conditions have been studied. As expected, substitution at the ortho position strongly affects the degree ofstereoselection tha
A simple resolution procedure using the Staudinger reaction for the preparation of P-stereogenic phosphine oxides

The resolution of a variety of (±)-P-stereogenic phosphines is achieved by exploiting the Staudinger reaction of a (±)-phosphine with enantiopure (1S,2R)-O-(tert-butyldimethylsilyl)isobornyl-10-sulfonyl azide. The resulting mixtures of diastereomeric phosphinimines are generally separable by fractional crystallization or flash chromatography. Subsequent acid-catalyzed hydrolysis provides the corresponding optically pure phosphine oxides in high yields.
SYNTHESE DIRECTE DE PHOSPHINES TERTIARIES RACEMIQUES ET DE CHLOROPHOSPHINES DISSYMETRIQUES
Chodkiewicz, W.,Guillerm, D.,Jore, D.,Mathieu, E.,Wodzki, W.
, p. 107 - 114 (2007/10/02)
Racemic tertiary phosphines are obtained from dichlorophenylphosphine by a "one pot" synthesis in two steps: (1) condensation of one equivalent of an organocadmium, and (2) substitution of the second chlorine by another organometallic compound.The phosphines liberated from the resulting complexes can be stabilised by direct complexation with cuprous salts.The monochlorophosphines can be isolated in the first stage when their cadmium complexes are submitted to ligand exchange with pyridine.
