General description

Tris(2,2,2-trifluoroethyl) phosphite is an organophosphorus compound that is used as a ligand in organometallic chemistry to enhance labialization in metal clusters and as a substitutional equivalent for carbon monoxide. It is also used as an electrolyte additive to improve the electrochemical performance and as a co-solvent for nonflammable electrolytes in Li-ion batteries.

Application

Tris(2,2,2-trifluoroethyl) phosphite was used in the synthesis of N-methoxy-N-methyl bis(2,2,2-trifluoroethyl)phosphonamide via the Arbuzov reaction with 2-bromo-N-methoxy-N-methylacetamide.

The N-methoxy-N-methyl bis(2,2,2-trifluoroethyl)phosphonamide was easily obtained via the Arbuzov reaction with use of commercially available tris(2,2,2-trifluoroethyl)phosphite, 2-bromo-N-methoxy-N-methylacetamide, and KF/alumina. The reaction of bis(2,2,2-trifluoroethyl)phosphonate with several aldehydes demonstrates the versatility of the method, which gives Z-unsaturated amides in good yields.

Of the various beyond-lithium-ion batteries, lithium-sulfur (Li-S) batteries were recently reported as possibly being the closest to market. However, its theoretically high energy density makes it potentially hazardous under conditions of abuse. Therefore, addressing the safety issues of Li-S cells

N-alkyl phosphoranimines were synthesized via the Staudinger reaction of four different alkyl azides with tris(2,2,2-trifluoroethyl) phosphite. N-adamantyl, N-benzyl, N-t-butyl, and N-trityl phosphoranimines were thoroughly characterized and evaluated as chain-capping compounds in the anionic polymerization of P-tris(2,2,2-trifluoroethoxy)-N-trimethylsilyl phosphoranimine monomer.
