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.

The reaction of C6H5(CH3)PNa with some alkyl halides in liquid ammonia was studied.The resulting phosphines were characterized by elemental analyses, NMR spectra, and by the reaction with trimethylsilyl azide giving trimethylsilylimino triorganophosphoranes. - Keywords: Alkylmethylphenylphosphines, N-Trimethylsilylimino Triorganophosphoranes, NMR Spectra
