설명

애플리케이션

Trimethyl phosphite is an organophosphorus ester with flame retardant property. It is generally used as a ligand to form coordinate complexes with transition metals.
Some of its other applications include:

• For N-alkylation of amino-9,10-anthraquinones in imidazolium-based ionic liquids without the use of base and highly polar organic solvents.
• To synthesize dimethyl phenylphosphonate by reacting with phenyl radical generated by the thermal decomposition of phenylazotriphenylmethane (PAT).
• To synthesize aryl phosphonates via P-arylation reaction with silyl triflates.
