General description
Trimethyl phosphite is an organophosphorus compound commonly used as a polymerization catalyst, coating additive, and as an intermediate in the synthesis of flame retardants. In addition, it is also used as an activating reagent in amide formation.
Application
Trimethyl phosphite can be used as a ligand in the synthesis of allyliridium phosphite complexes by direct reaction with allyliridium 1,5-cyclooctadiene complex.
