Triethyl phosphite, 98%, Thermo Scientific Chemicals

Description

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.
