Nitroethylene synthesis

8synthesis methods
Nitroethylene is best prepared by dehydration of 2-nitroethanol using phthalic anhydride (eq 1). It can also be generated for reactions in situ from several precursors, especially 2-nitroethyl phenyl sulfoxide.

Yield:3638-64-0 80%

Reaction Conditions:

with ferric nitrate for 0.5 h;Milling;

Steps:

Grind-stone method of β-nitro styrene synthesis

General procedure: Known amounts of unsaturated acid (0.1 mol), PEG (0.02 mol) and Fe(III) or Mn(II) nitrate (0.12 mol) were taken in a mortar and ground with a pestle till the reaction mixture became homogeneous. After completion of the reaction, as confirmed by TLC, about 2 % Na2CO3 solution was added to the reaction mixture till it is neutralized. Reaction product was extracted by dichloromethane (DCM) or dichloroethane (DCE), dried with sodium sulfate and purified by column chromatography. Binary solvent mixture of ethyl acetate and hexane (3:7) was used as eluent to obtain pure product.
