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.

Check Digit Verification of cas no
The CAS Registry Mumber 10497-05-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,0,4,9 and 7 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 10497-05:
(7*1)+(6*0)+(5*4)+(4*9)+(3*7)+(2*0)+(1*5)=89
89 % 10 = 9
So 10497-05-9 is a valid CAS Registry Number.

Synthesis and Characterization of Silylated Phosphonium [P(OSiMe3)4]+ and Phosphate [O2P(OSiMe3)2]- Salts
Felgenhauer, Paul,Labbow, René,Schulz, Axel,Villinger, Alexander
, p. 9348 - 9353 (2018)
Starting from an optimized synthesis of silylated phosphoric acid, OP(OSiMe3)3, a borate salt bearing the [P(OSiMe3)4]+ cation was generated in the reaction of OP(OSiMe3)3 with [Me3Si-H-SiMe3][B(C6F5)4], isolated, and fully characterized. Analogously to the protonated species, phosphoric acid (H3PO4) reaction of OP(OSiMe3)3 with a base led to the formation of the unknown [O2P(OSiMe3)2]- anion, which could be crystallized as potassium salt and structurally characterized, too. Both [P(OSiMe3)4]+ and [O2P(OSiMe3)2]- can be regarded as the formal autoprotolysis products of OP(OSiMe3)3.
