Silylphosphines and Related Compounds

Several syntheses of trimethylsilylphosphines have been described. Thus the silylphosphines (59) have been prepared by a Grignard-type reaction. 

Treatment of (59) with halides of the higher Group IV elements leads to the analogous phosphines (60). Phosphides continue to be of use in the preparation 

Silylphosphines have been applied to the synthesis of other phosphines and that of silanes containing no phosphorus. For example, the bisphosphine (64) 

Treatment of silylphosphine (68) with amines in the gas phase gives quantitative yields of silylamines. Pyrolysis of (68) (using deuterium labelling)
