Triethyl phosphite → 4-Nitro-3-methyl-2-butene-1-phosphonic acid diethylester

Participants

Reaction Steps

To 0.1 Mol of 1-bromo-3-methyl-4-nitro-2-butene was added 0.1 Mol of triethylphosphite. The reaction was started by immersing the mixture into a 50° C. bath and completed under continued removal of bromoethane by distillation. The residue was purified via column chromatography over silica gel using ether as solvent. The product was obtained as a yellowish liquid.
