Overview

Application

Diethyl cyanomethyl phosphonate is used as an intermediate in Horner-Emmons reaction for the synthesis of substituted nitriles and their amide and heterocyclic derivatives. It is known as a modified Wittig reagent used in the preparation of alpha, beta-unsaturated nitriles from ketones or aldehydes like 3-hydroxy-3-methylbutanal. It reacts with epoxides and nitrones to prepare cyano-substituted cyclopropanes and aziridines respectively. It is actively involved in the synthesis of alpha-arylated alkanenitriles via reaction with aryl iodides in presence of CuI.
