Colorless liquid | [Uses]
Tris(trimethylsilyl) phosphite (TMSPi) is a film-forming additive for high voltage cathode material in lithium-ion batteries. Tris (trimethylsilyl) phosphate is cleaved by alkali-metal fluorides, nitrates, and acetates at give the trimethylsilyl esters of the corresponding acids. | [Definition]
ChEBI: Tris(trimethylsilyl) phosphate is an organosilicon compound that is phosphoric acid in which the three hydroxy groups are substituted by (trimethylsilyl)oxy groups. It is a phosphoric acid derivative and an organosilicon compound. | [Preparation]
Tris(trimethylsilyl)phosphine is prepared by treating trimethylsilyl chloride, white phosphorus, and sodium-potassium alloy:
1/4 P4 + 3 Me3SiCl + 3 K → P(SiMe3)3 + 3 KCl | [General Description]
Tris(trimethylsilyl) phosphate has been investigated as a novel film-forming additive for LiNi0.5Co0.2Mn0.3O2 cycling at high cut-off potential in LiPF6-based electrolyte. Tris(trimethylsilyl) phosphate [Tris(trimethylsilyl) ester of phosphoric acid] undergoes dealkylsilylation reaction with alumazene to yield heteroadamantane molecule. | [Reactivity Profile]
Tris(trimethylsilyl)phosphine and its more reactive derivative lithium bis-(trimethylsilyl)phosphide·2tetrahydrofuran are very useful reagents for the preparation of compounds with a single or a multiple element phosphorus bond. They react readily with various element halides, with carboxylic acid chlorides, and with carboxylic esters, as well as with other organic electrophiles via a substitution of lithium and/or a cleavage of the weak polar Si-P bonds. | [Flammability and Explosibility]
