It is used as a reducing agent; can react with electrophiles to form phosphonates or phosphates; forms a stable complex with copper(I) iodide. Triethyl phosphite is a very good nucleophile. The carbon adjacent to the bromine is the most electrophilic position, and phosphorus is the only nucleophile. Triethyl phosphite displaces the bromine in an SN2-like process, and back attack by the bromide which is released generates a phosphonate product, in which the α-protons are strongly acidic. Triethyl phosphite is used as a ligand in organometallic chemistry and as a reagent in organic synthesis. It is used as reference to phosphoric acid standard in 31P NMR spectroscopy. It acts as a reducing agent to prepare 2-phenylindazole from o-nitrobenzylidineaniline as well as reacts with electrophiles to get phosphonates. It forms a stable complex with copper(I) iodide. It finds application in a modified Staudinger reaction for the alkyl bromide to an amine through the azide. Further, it is also used in the preparation of 3-phenyl-2-substituted indoles by reacting with beta-nitro styrenes.
