A mild and efficient method for the synthesis of tertiary phosphines and ditertiary phosphines has been developed. In the presence of cesium hydroxide, molecular sieves and DMF at room temperature, various secondary phosphines and alkyl bromides were examined, and the results have demonstrated that this methodology offers a general synthetic procedure to produce tertiary phosphines in moderate to high yields. Optically active tertiary phosphine synthesis is also described.

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
A GENERAL SYNTHESIS OF OPTICALLY ACTIVE PHOSPHINES, PHOSPHINITES AND THIOPHOSPHINITES FROM ALKYLTHIO(ALKYLSELENO)PHOSPHONIUM SALTS AND TRIS(DIMETHYLAMINO)PHOSPHINE AS A THIOPHILIC AGENT

Tris(dimethylamino)phosphine was found to be a suitable thiophilic reagent which converts optically active alkylthio(alkylseleno)phosphonium salts into chiral tertiary phosphines and phosphonites with a high stereoselectivity.The first synthesis of optically active thiophosphinites from bis(alkylthio)phosphonium salts and tris(dimethylamino)phosphine is also reported.
