Silylphosphines synthesis

The most direct synthesis is performed by reaction of a dihalo compound with a tricoordinated phosphorus compound including a reactive P—Y bond (reaction 101). This synthesis, first used with secondary phosphines, the corresponding phosphides or diphosphines (Y = H, Na, K, PPh2)2b,38°, has subsequently been developed also with silylphosphines (Y = SiMe3),132,381-383 which are easier to handle (reaction 102). The same kind of cyclization by intramolecular alkylation can be achieved using a functional phosphine prepared in a multi-step synthesis380,384,385 (reaction 103).

The synthesis of tris(trimethylsilyl)silylphosphine (Scheme 2) yielded colorless crystals that could easily be purified by vacuum sublimation. Contrary to the observations made by Uhlig [3] with the Si(CH3)3 substituent, we were not able to introduce more than one bulky hypersilyl group to PHj. 

Silylphosphines have been extensively used in the synthesis of P(III)=C...
