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.

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.
