Chlorination of conjugated nitroalkenes with iodobenzene dichloride or sulfuryl chloride to give target α-chloronitroalkenes in good yields is described. Details of the procedure depend on the donating ability of the nitroalkene substituents. The activity of the described chlorinating agents increases in order 'PhICl 2/Py' 2Cl 2' 2Cl 2/HCl' with the former producing the best yields for highly donating substrates and the latter for non-activated groups. An autocatalytic role of hydrogen chloride and the chemoselectivity of chlorination were also demonstrated.

β-Chloro-β-nitroolefin derivatives 2 were prepared from the reaction of β-nitroolefins 1 with HCl/DMF/Oxone system in moderate to good yields.
SYNTHESIS OF 2-HALOGENO-2-NITROETHENYLARENES
Aleksiev, D. I.,Ivanova, S. M.
, p. 1845 - 1848 (2007/10/02)
A series of 2-halogeno-2-nitroethenylarenes were obtained as a result of the condensation of halogenonitromethanes with aromatic (heterocyclic) aldehydes in the presence of catalytic amounts of ethylenediamine and also by the addition of halogenonitromethanes to butylarylimines in acetic anhydride.
