What is TRIS(TRIMETHYLSILYL)PHOSPHINE?
The Uses of TRIS(TRIMETHYLSILYL)PHOSPHINE
Tris(trimethylsilyl)phosphine is a more stable analog of phosphine, but retains high reactivity due to the presence of the weak polar Si–P bond. It is nucleophilic and readily reacts with a range of electrophiles. Reaction with alkylating agents provides substituted phosphines, with acid chlorides phosphaalkenes can be obtained, and phosphabenzenes can be synthesized upon reaction with pyrylium salts. It can be used as user-friendly phosphorus source and alternative to phosphine gas, precursor of (Me3Si)2PLi, covalent synthon for the anion P3?).
