Description

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.

Packaging
